If you have used Apple products for a while, you would by now have become very well acquainted with the fact that Apple does not provide options users want. However, it does provide options which they want and only they want.
With the introduction of the multitasking feature in iOS4, Apple made a lot of people happy, happier than they would have been when multitasking first came out. However, here is the catch, you cannot disable Multitasking or wallpaper support on an iPhone which supports them.. duh.
Of course, Apple also put in restrictions for some users to not run Multitasking and Background Wallpaper for users who had anything lower than a iPhone 3G and iPod Touch 2G. While I understand the fact that those devices did not get an option to enable those features, what beats me is the fact that Apple decided themselves that users will not be able to disable those features on supported devices unless theyâ€¦ jailbreak their devices.
Now this in itself sounds a bit crude, because users have no control over what they can do with their iPhone or iPod Touch, and unless Apple releases a new update with a breakthrough feature to disable multitasking and background wallpaper there is no way out unless you, well, jailbreak.
And yes, when Apple does release an update to disable multitasking and background wallpaper, a collective gasp will go around among Apple fanboys appreciating the fact that Apple was very generous in allowing them to disable features with on their devices which they should have been able to do in the first place itself.
Anyways enough of it, if you want to disable multitasking and background on your newly installed iOS 4 device, you can only do it with iPhone 3G and iPod Touch 2G which were not yet officially supported. Jailbreaks for iPhone 3GS, iPhone 4 and iPod Touch 3G might take some more time to come out, so until then just keep praying that either a jailbreak comes out first, or Apple realizes that users have choices too and release an update to disable those features.
