While yesterday’s 2.0.1 firmware update for Apple’s iPhone seems to be providing users with an added level of stability and responsiveness, it looks like at least one subset of iPhone users has been left a bit less than satisfied. Some users that paid the requisite fee to have their Vodafone-branded handset unlocked for international roaming are finding that the 2.0.1 update is frying the unlock, rendering their phone useless without a Vodafone SIM. Some people have had luck with a full restore, but more than a few seem to be completely out of luck. Frustrated? We certainly would be, especially considering the considerable sum that the unlocking process commanded. We’re sure Vodafone / Apple will work this one out, but in the mean time we can add this to the list of iPhone related issues, failures, and glitches.
