20-something firmware magician GeoHot (George Hotz) has already been sued by Sony for jailbreaking the PlayStation 3, and caused a major stir in the iPhone dev community when he released limera1n -- has now been invited by Microsoft to have a stab at jailbreaking Windows Phone 7 devices.
The invitation has been handed out, with WP7 lead Brandon Watson offering to ship Hotz a device so that he can give it a go. Microsoft, of course, has said that it fully supports "official homebrew" development for WP7 and met recently with the Chevron WP7 team to discuss community and development-related issues.
"#geohot if you want to build cool stuff on #wp7, send me email and the team will give you a phone - let dev creativity flourish #wp7dev".
Hotz can work on WP7 without worrying about adding to his legal dilemmas. Apple is also trying to find ways to end jailbreaking on their devices, according to NetworkWorld Apple said
Current jailbreak technologies now in widespread use utilize unauthorized modifications to the copyrighted bootloader and operating system, resulting in the infringement of the copyrights in those programs.
The exploit used by Chevron WP7 is due to be patched in the January update for Windows Phone 7, so GeoHot will need to look elsewhere. Still, he's done it twice before, so we wouldn't be at all surprised if he can do it again.
