p>George Hotz, the eminent iPhone hacker that was part of the team that first unlocked their iPhones, continues to hack away at the security that prevents iPhone users from mucking around with activations, unlocks, and unofficial 3rd party applications. Specifically, he found a couple of errors in the bootloader that theoretically should allow folks to install custom firmware to their iPhone, or just re-flash earlier, less locked versions of their cell radio. One of the hacks uses hardware, the other uses software. It seems that he's doing well at RIT and I'm glad to see that he hasn't moved on to other devices.
