If you have a jailbroken iPhone, you might want to backup your SHSH Blobs to Cydia. SHSH blobs are required for older OS so that you can jailbreak newer versions of iOS. If you are already using iOS 4, it is highly recommended by the Dev Team to backup your SHSH Blobs locally or on Cydia.
If you want to backup iOS 4 SHSH blobs locally, you can use a tool called TinyUmbrella to backup your iOS 4 SHSH blobs so that you can use it to jailbreak when you upgrade to iOS 4.1. To backup your SHSH blobs download TinyUmbrella and run it, connect your iPhone or iPod Touch to the computer and click on the “Save My SHSH” button to start the backup process.
TinyUmbrella is available for Windows, Mac OS X and Linux. The update is a one click process, so do it before iOS 4.1 hits the street to be on the safer side. You can download TinyUmbrella for Windows from here, Mac OS X from here and Linux from here. More download links can be found at the official site here.

Apple has released an updated version of iOS 4 named as iOS 4.1 beta for iPhone 4, iPhone 3GS, iPhone 3G, iPod Touch 3G and iPod Touch 2G. The new version has several changes which are intended for developers to work with.
If you are an Apple Developer, you can download iOS 4.1 beta from the Apple developer site here to try out and build applications with. However, if you are an iPhone 4 user do not expect this to fix the Death Grip Antenna issue, we earlier reported that iOS 4.1 does not fix Antenna issues, so these issues are purely hardware related.
Also, if you have jailbroken iPhone, it is highly advisable to stay away from this update until the Dev team and others work on a new jailbreak for iOS 4.1. New features in iOS 4.1 are not very noticeable except for a change in the network signal bars.
iOS 4.1 also lays foundation for Game Center which has not yet launched. In addition to that, iOS 4.1 does not have support for the iPad yet, so it iPad users may have to be content with using iOS 3.2 for now. Are your hands itching? Go ahead and download iOS 4.1 from the Apple Developer site here then.
Apple has released a new beta of iOS 4, tagged iOS 4.1 to developers. The new version of iOS 4 does not include much changes and is not yet ready for the iPad.
Many people thought that a software update would fix the iPhone 4Antenna reception issues, but there are reports from Mobile Crunch which suggest that it does not do it. This means that Apple will most likely have to recall the faulty iPhone 4 from the market, which again will cost them billions of dollars.
Mobile Crunch have also included a video which demonstrates that the Antenna issues still exist after upgrading to iOS 4.1, check the video below.
iOS 4.1 has some noticeable differences where the signal bars are slightly bigger and the phone also has lesser bars. If you depend on Jailbreaking the iPhone or Unlocking iPhone you are advised to stay away from this update. We will keep you posted when iOS 4.1 jailbreaks and iOS 4.1 unlock becomes available.
