Just one comment. Apple iPhone 3Gs wont be upgradable to iOS 5.x. iPhone 4 will.
iOS 5 is expected to be revealed at WWDC in June. Although the iPhone 3GS is currently still on the market, Apple has previously discontinued software updates for older iOS devices like the original iPhone 2G -- and more recently the iPhone 3G.
And who knows, if iOS 5 requires a minimum of an Apple A4 chipset to run at acceptable performance levels, then maybe Murtazin might have something. We'll have to wait for WWDC to find out.
What do you think, iPhone 3GS owners?
UPDATE: Some folks are pointing out that Murtazin said iPhone 3Gs, not iPhone 3GS, as in he meant the plural form of iPhone 3G. And since they didn't get iOS 4.3, it stands to reason they wouldn't get
