iPhone 3194/1015 Error on Restore to 3.1.3 from iOS 4

Many users who were trying to downgrade iOS 4 to 3.1.3 have been facing a 3194 error. This error occurs when users try to restore the 3.1.3 firmware while downgrading from .

So is this issue fixable? Maybe. There was a forum post on TiPb which points users to a fix for this issue, apparently that is the same fix we listed in this post and it might not work when you are downgrading from iOS 4 to iPhone OS 3.1.3.

The problem actually lies with the fact that Apple signs the firmware now and you cannot upgrade or downgrade an iPhone using a firmware that Apple has not signed anymore, so this issue might go away if you use an older firmware which is signed by Apple.

Once again, using an Apple signed firmware may not fix this issue and we are actively researching on things that would help users to downgrade their iPhone or running iOS 4 to iPhone OS 3.1.3.

Downgrade iOS 4 to iPhone 3.1.3 on iPhone/iPod Touch

Apple recently released the iOS4 firmware update for the iPhone 3G, 3GS and iPod Touch users. Users updated to the new firmware anticipating new features and improved performance. Nevertheless, for some of them the   opposite occurred, especially for iPhone 3G owners. Most of the iPhone 3G users are reporting very slow performance and applications crashing. The main cause of this problem is the slow processor and the low amount of RAM in the iPhone 3G.


Now there is no official way to downgrade to OS 3.1.3 from iOS4, but there is always an unofficial way. Here are the steps to downgrade from iOS4 to OS 3.1.3 :

1) First navigate to c:\windows\system32\drivers\etc\and open the hosts’ file in notepad. To do so, right click on the file and select Open With->Notepad. At the end of the document, add this string gs.apple.com.

2) Now connect your iPhone to iTunes in recovery mode. To do so, first switch off your device. Then press the Home button on your handset and connect the USB cable. As soon as you connect the USB cable, the device will boot up and a Connect To iTunesscreen will be displayed. Users can now stop pressing the Home button.

3) Fire up iTunes now. You will see your iPhone/iPod Touch detected in recovery mode. Now, whilst pressing the Shift key for Windows users or Alt key on the Mac platform, click on the Restore option.

Now just select the original OS 3.1.3 and voila, you are done. Now you can again enjoy OS 3.1.3 on your iTouch device.


512 MB RAM for Apple iPhone 4

It has been just confirmed by Apple, as reported by MacRumors, that the iPhone 4 showcasing the brand new IOS 4 comes with 512 MB RAM. This boost in memory is sure to give a notable performance jump to the iPhone 4. The earlier iPhones iPhone 3G had 128 MB and iPhone 3GS had 256 MB RAM respectively.

The higher amount of RAM will be particularly useful as Apple finally brings multitasking to its IOS 4. This multitasking feature has been present in Blackberry and Android for quite some time now. This is also the reason why the older iPhones will not get multitasking they simply do not have enough RAM to support it.

Apple unlike other manufacturers have not yet released a spec-sheet of the exact hardware for the iPhone 4. They are laying greater emphasis on the applications and features of the phone rather than the hardware.

The increased amount of RAM is not the only new feature for iPhone to boost. It also comes with a gaming social network called Game Centre where players can meet and greet, show off achievements and make friends. The iPhone is slated to come with a 5.0 MP camera. This will enable it to shoot 720p HD videos and even edit them with the iMovie app.

The iPhone 4 sporting the beautiful IOS 4 is surely the product to look forward to and like all Apple products, it has the potential to be a definite trend setter.

Live Coverage of iPhone OS 4.0 Apple Event

The Apple iPhone OS 4.0event is going to start in just a few minutes now. As usual the expectations are high from this event. Many iPhone users are hoping that the new version of iPhone OS will support multi-tasking and bring in battery life enhancements as well. Apple had recently released the Apple iPad which has got ravishing reviews all over the net. Apple said that they have managed to sell 300k iPad in the first couple of days.

It is not confirmed but users are also expecting Apple to release iPhone HD or iPhone 4G. Rumors also say that Apple will launch a refreshed line-up of the Macbook series.

Live Updates :

The event started a few minutes ago. Sorry for the delay in the live update guys!

10:00AM : Steve Jobs enters!

10:01AM 10:10AM : Steve Jobs before introducing us to the iPhone OS 4.0, tells us about the enormous success of the iPad. Steve said that over 250k books have been downloaded from the iBook store until date. He also said that Apple has managed to sell 450k iPad within a few days of its release. Steve also says that currently the App Store has 3.5k apps for the iPad and the number is increasing at a tremendous rate.

10:12 AM : Steve finally announces the iPhone OS 4. He says that the OS will ship this summer and a preview version for developers will be released today.

10:15 AM : He says that the iPhone OS 4 will have more than 1500 API for developers.

10:18 AM : New features of iPhone OS 4 include 5x digital zoom, tap to focus in videos, and Bluetooth keyboards.

10:19AM : Steve announces what all iPhone users have been eagerly waiting for Multitasking!. He says We weren’t the first to this party, but we’re going to be the best. Like cut and paste — it’s better than any other implementation. It’s really easy to implement it in a way that really drains battery life. And, it’s really easy to implement it in a way that reduces the performance of the foreground app and makes your phone feel sluggish.

After this Steve Jobs gives the viewers a demonstration of the multi-tasking on the iPhone. He uses the Home button on the iPhone to switch between multiple applications.


10:21 AM : Steve says that the iPhone OS 4 will provide seven multitasking services. Tim Westergren from Pandora comes up on the stage and demonstrates the Pandora application on the iPhone. The application can now run in the background while continuing to stream the audio.

The second demonstration is from a Skype representative. He demonstrates that now it is possible to navigate away from the Skype app and be still able to receive calls on it.

10:27AM : Scott now tells us about background location services. He says The next is background location. There are two classes of apps that want to use your location in the background. One is turn by turn directions, like TomTom. The problem is, until now, if you left an app like TomTom, you’d stop getting directions.

He says that the location of the users can be tracked either by using A-GPS or GPS. Nice move by Apple here, since GPS consumes a lot of battery power.

10:31AM : Scott :With all these location services, we take privacy very, very seriously. We’re taking it several steps further in iPhone OS 4. First, we’re adding an indicator to the status bar if something is tracking your location. Next: we’re adding fine-grained settings so you can enable/disable location on per application.

Whoa! Awesome move by Apple here. Sure gives adequate respect to the privacy of the iPhone users.

10:35AM : Scott then introduces us to another multitasking service task completion. Scott says The next is task completion. One is like Flickr: sometimes photos can take a while to upload. With task completion, Flickr can continue to upload those photos in the background when you browse away. Our last service: fast app switching.Impressive!

10:36AM : Scott goes and Steve is back on the stage. He introduces another new feature in the iPhone OS 4 which is Folders. He demonstrates this by dragging and dropping one app over the other and a folder is automatically created. The folder is automatically assigned a name, but it can be edited. These folders can be used in the dock as well.

iPhone OS 4.0 Mail

10:39AM : Steve then announces the enhanced version of Mail. There is now unified inbox, and now its possible to organize mails by thread. Steve also says that there are other minor changes in the Mail application.

10:41AM : Steve then announces the iBook application for the iPhone. He says We’re really excited about this. Just since rolling it out on the iPad, we’ve had so many requests to bring this to the iPhone — of course, we were already doing that. We think customers will really enjoy this on their iPhone or iPod touch.

10:43AM : Buy your books once and read them anywhere. We’re wirelessly syncing pages and bookmarks automatically. And just like on the iPad, we’re supplying a free book: Winnie the Pooh. You know, we labored over that choice, which to include!

10:45AM : Scott is back on the stage and he announces that Apple is now making APIs available to developers to encrypt all the data inside their application as well.

10:46AM : Scott then introduces us to the sixth new major feature of the iPhone OS 4.0 Game Center. A developer preview is only present in iPhone OS 4.0 though. He says Gaming is extremely popular on the iPhone and iPod touch. In fact, we have over 50k titles… let’s look at the competition. If you look at dedicated gaming devices like the PSP and DS, this just blows them out of the water. We wanted to make this even better — we’ve added a social gaming network. We do automatic matchmaking, we’ll find others with a similar ability and match them against you. You can see how you’re progressing in a game with achievements.Looks like Apple is taking a shot at Xbox Live service from Microsoft here.

10:48AM : Steve is back on the stage and then introduces us to the last feature of the iPhone OS 4.0 iAd, Mobile Advertising. "He says On a mobile device, search is not where it’s at, not like on the desktop. They’re spending all their time on these apps — they’re using apps to get to data on the internet, not generalized search.

10:52AM : We want to be even more interactive than the ads on the web, and we want to get some of that interactivity from video. The ads keep you in your app…People don’t click on ads because you get yanked out of your app. Because iAd is in the OS itself, we’ve figured out how to do interactive and video content without ever taking you out of your app!

The user can return to their app any time they want. We think the user will be much more interested in clicking on these things because they won’t pay the penalty for doing so. You can add iAd opportunities in an afternoon — we’re going to host and deliver the ads, and we’ll give developers an industry standard 60% of the revenues.


10:55AM : Steve then gives us a demo of the new iAd platform. He shows the views a Toy Story 3 movie ad, which is coming out this June. The ad is done in HTML5. Uh huh! Adobe! The demo of the new iAd platform is pretty impressive. The iAd platform is heavily integrated into the iPhone OS 4.0.

11:00AM : The demo is over and then Steve says That’s an example of 3 ads that are very easy to make. In addition to ad agencies being able to make these things, there are hundreds of thousands of iPhone app devs who know how to make these things. Emotion plus interactivity. The ads keep you in your app, so you’re much more likely to click on then and explore.

11:01AM : Steve then says that the preview version of iPhone OS 4.0 Developer will be available from today itself at developer.apple.com. He then says that the iPhone 3GS and iPod Touch 3G will run pretty much everything.Time for some bad news guys.

Steve – For iPhone 3G and iPod touch 2nd gen, they will run many things, but not everything — they will not support multitasking, the hardware just can’t do it.

Steve then announces that the iPhone OS 4 will be available for the iPad this fall.

The event is more or less over. There is a Q&A session which follows.

Unlock iPhone 3.1.3 Baseband 05.11.07 With Blacksn0w RC2

Finally some good news for people who upgraded to OS 3.1.3 or have been pushing it back because there haven’t been any unlocks for baseband 05.11.07.

iPhone OS 3.2 Coming Soon?

Even though there are news that Apple will be releasing the in near future, developers are busy updating their apps for OS 3.2.

Flickr iPhone OS 3.2 Update

A recent update to the app for iPhone shows that they have added new changes to support iPhone OS 3.2, which means that the app will definitely be a part of the , which will run on iPhone OS 3.2.

The update to the Flickr app was released on March 11th 2010. The changelog for the Flickr app says "Support for OS 3.2", which went past through the app store approval panel, who would have definitely seen the changelog before approving the app.

So are we going to see Apple releasing iPhone OS 3.2 for the iPhone and iPod Touch soon? Or will be released only after Apple starts shipping the iPad next month? Considering that there are less than 3 weeks before the iPad starts shipping, we might see a iPhone OS 3.2 update by end of this month or so.

Another Indication That iPhone OS 4.0 Will Introduce Multitasking

Apple-iPhoneBack in January, we reported that Apple iPhone OS 4.0 might introduce a host of improvements including support for full-fledged multitasking. Now, Apple Insider has uncovered further evidence, which corroborates our original story.

Ever since the introduction of 3rd part apps, multitasking has been one of the most requested (rather demanded) features. The iPhone OS has traditionally prevented third party apps from running in the background. However, this has always been an artificial restriction, rather than a technical limitation. In fact, Jailbroken iPhone’s have had multitasking capability for quite some time.

At the moment, very little is known about the upcoming firmware update. However, sources with a proven track record have confirmed to Apple Insider that, “The Cupertino-based company has developed a “full-on solution” to multitasking on the iPhone OS”. The source also teased that iPhone OS 4.0 will feature a “multi-tasking manager that leverages interface technology already bundled with its Mac OS X operating system”. Gizmodo believes that the interface technology in question is Expose. What do you think? Are you excited at the prospect of seeing multitasking in iPhone? Don’t forget to let us know.
