When Apple fired a warning shot earlier this week, many folks in the hacker community were unsure whether the company was serious about re-locking unlocked iPhones or if it was simply bluffing in order to discourage would be hackers. Well, looks like we have our answer: version 1.1.1 makes good on Apple’s threats by re-locking iPhones running non-AT&T SIM cards and disabling many 3rd party applications. Yikes. Unlocked iPhone users are reporting various degrees of success by either swapping out the SIM card for a legit AT&T card pre-upgrade or re-activating afterward using a valid AT&T SIM. Regardless, this much is clear: if you have an iPhone that’s either unlocked or loaded with 3rd party apps, it’s not going to be the same after the update, if it even works at all.
