SIM Lock Removal

While initially iPhones were only sold on the AT&T network with a SIM lock in place, various hackers have found methods to "unlock" the phone; more recently some carriers have started to sell unlocked iPhones. More than a quarter of iPhones sold in the United States were not registered with AT&T. Apple speculates that they were likely shipped overseas and unlocked. AT&T has stated that the "iPhone cannot be unlocked, even if you are out of contract".

On November 21, 2007, T-Mobile in Germany announced it would sell the phone unlocked and without a T-Mobile contract, caused by a preliminary injunction against T-Mobile put in place by their competitor, Vodafone. On December 4, 2007, a German court decided to grant T-Mobile exclusive rights to sell the iPhone with SIM lock, overturning the temporary injunction. In addition, T-Mobile will voluntarily offer to unlock customers' iPhone after the termination of the contract.

On carriers where removal of the iPhone's SIM lock is allowed, the carrier can submit a request to Apple which will then remove the carrier locking on the next restore of the iPhone through iTunes. Note that in certain countries, where unlocked phones are required to be available by law, the iPhone is sold without a contract and without a SIM lock; on average, such units carry prices of US$700+ for the 8 GB model. Examples include Hong Kong, Italy, New Zealand, and Russia. In Australia, all three carriers (Optus, Telstra, and Vodafone) will also provide an unlock after requesting it from the carrier.
