George "Geohot" Hotz broke open iPhone and broke open PlayStation 3. Apple wasn't happy and Sony has taken Hotz to court.
What would Microsoft do if Hotz broke open Windows Phone 7?
In fact, Microsoft wants to send Hotz a Windows Phone 7 handset so he can get cracking.
"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," tweeted Brandon Watson, Windows Phone 7 team lead.
Hotz's jailbreak for PS3 allows homebrew applications and pirated games to run on the console. Sony's trying to stop him distributing it, but Hotz is fighting The Man every step of the way.
