George Hotz, in a post on iphonejtag.blogspot.com, claims to have successfully completed a full unlock of the iPhone using a hardware hack. The current method, which Hotz says “involves taking apart your phone and doing some complicated soldering, with a high probability of a bricked phone,” allows all hardware to be removed following the unlock, and allows the iPhone to work with an active SIM card from any GSM carrier.
According to the post, information and instructions on how to perform the unlock will be released one week from today. At that point, Hotz claims, it may be possible to unlock the phone without risky hardware modifications.
Video of the unlocked iPhone in action is now available on YouTube..
