Last week a number of iPhone unlocking claims were made by different individuals with one confirmed success. A second company (iPhoneUnlocking) also announced they had a software-only solution, but according to a press release, they claim to have been contacted by AT&T's law firm to prevent the release of their unlocking service.

The sale of unlocking codes is on hold after the company received a telephone call from a Menlo Park, California, law firm at approximately 2:54 a.m. this morning (GMT).

After saying they were phoning on behalf of AT&T, the law firm presented issues such as copyright infringement and illegal software dissemination. Uniquephones is taking legal advice to ascertain whether AT&T was sending a warning shot or directly threatening legal action. The logistics of different continents as well as it being a weekend factors into how the situation develops.

The original iPhone unlocking site (iPhoneSimFree.com) has not revealed if they have been similarly approached by AT&T.
