Apple’s (NSDQ: AAPL) ambivalence about whether it would actively fight the hacking of the iPhone seems to have ended, with the iPhone 1.1.1 update disabling the ability to use the handset on other networks, as well as the “jailbreak” hack which let people install unsupported software. It goes a bit further than that, with one user saying that “after the 1.1.1 patch was installed, it wiped out all of the third-party applications he had installed on a second iPhone” according to InfoWorld, so it’s not just preventing the hack from working but actively trying to undo what the hack allowed. The unlocking crowd are right in there to fix the problem, or break Apple’s fix depending on your point of view. Engadget notes that iPhoneSIMfree users will need the original AT&T (NYSE: T) SIM card to reactivate it after the update, although some other unlocking solutions can’t be reactivated at all. The updates seems to fix some minor flaws, and a critical one. Gizmodo has a fairly comprehensive post on it.
