A New Jersey teenager has figured out how to make Apple's iPhone available on other wireless services besides AT&T, removing a major frustration for thousands of consumers.

And in an exclusive interview on CNBC, 17-year-old George Hotz revealed his motivation for unlocking the device: "It was fun."

"This was a good use of a summer," he said during the live interview Friday afternoon. "I became obsessed with unlocking this thing."

When Apple introduced the iPhone in July, it made the device available only on AT&T's wireless service, prompting widespread complaints among consumers. Hotz was able to unlock the device so that he can use it on his family's T-Mobile service.
