Some of the new cell phones are locked by the wiring on the circuit board. I have seen postings that told people which wire to cut to disable the lock. > I have several Motorola, GSM that I want to unlock from AT&T. I own > them. And I have extra SIMs. Is AT&T required to unlock them if I request? AT&T can unlock them but my experience with other providers is that they will not do it. I would expect those to be unlocked by entering an unlock code. You can sometimes find the unlock codes on the internet but if you do not enter them correctly you may completely disable the phone. Some independent cell phone stores will unlock a phone for a price. I only buy my cell phones from independent cell phone stores already unlocked. -- Robert Blair
