From the Dept. of Don't Say We Didn't Warn You comes another stern advisory that Apple's upcoming iPhone firmware update will pretty much break any hacks you might have accomplished. The semi-anticipated Ver. 1.1.3 (navigation by triangulation!) disables jailbreaks, makes it impossible to downgrade to an earlier firmware and spits on any unofficial third-party apps. Early hack forecasts say 1.1.3 will be much more of a challenge to jailbreak, too, so be patient or be sorry.
Warning: Do not update to iPhone 1.1.3 if you want unofficial third-party apps [iPhone Atlas]
