Teen Hackers Foil New iPhone Limits

A group of teenage thorns in Apple's side have been the first to release "jailbreak" software for the latest iPhone 3GS, the Wall Street Journal reports. The hackers, in the latest round of what Steve Jobs calls "a cat-and-mouse game with his top engineers," created software that lets iPhone users unlock their phones and download applications not approved by the company.

The teens say they decided to step up when an older group of hackers opted to sit on their jailbreak software until the next iPhone model is released. Apple—which warns that jailbreaking invalidates warranties—has a copyright case pending on phone modifications, but the teens insist they're doing nothing wrong.  "Apple doesn't have the right to tell me what I can put on my phone," said one 15-year-old boy. "I only do hacking that helps people." (More Apple stories.)
