Things are going fast. iPhone 1.1.3 is now available through your iTunes. If you have synced and click Check for update, you may see this thing. Notice if you are using AT&T and other official carrier of iPhone, and you didn’t install and use 3rd party native applications, you can go for upgrade now.
But, if iPhone is anySIM unlocked or jailbroken, you cannot go for upgrade. As early report confirmed this update will break and ruin all the unlocked iPhone. It will also break the 3rd party native applications. The worse thing is that some reports rumoured after updated to 1.1.3, you cannot go back to 1.1.2 and use the iPhone correctly. The iPhone will then turns to be iBrick.
This news is true unless someone found the way out to break Apple again. And it may also applied to iPod Touch update.
Note to those TurboSIM (and those who use hardware trick) users, since jailbreak may not be able in 1.1.3 right now, it may not work correctly after you updated 1.1.3.
