Per Appleinsider: http://www.appleinsider.com/article...one_unlocking_may_cause_permanent_damage.html "Apple said Monday that many of the unauthorized iPhone unlocking programs available on the Internet cause irreparable damage to the iPhone's software, which will likely result in the modified iPhone becoming permanently inoperable when a future Apple-supplied iPhone software update is installed. The Cupertino-based company said it plans to release the next iPhone software update, containing many new features including the iTunes Wi-Fi Music Store, later this week. "Apple strongly discourages users from installing unauthorized unlocking programs on their iPhones," the company wrote in a statement to the press. "Users who make unauthorized modifications to the software on their iPhone violate their iPhone software license agreement and void their warranty." Apple added that the "permanent inability to use an iPhone due to installing unlocking software is not covered under the iPhone's warranty.""
