GeoHot is getting around lately, not only has he helped in the cracking of the iPhone but he released the PlayStation 3 root key and custom firmware. He has been pretty mad at both Apple and Sony about their stances on jailbreaking, but has said on his website he likes Microsoft's approach to homebrew and wants to try Windows Phone 7.
GeoHot said "perhaps a more appropriate way to deal with jailbreakers, I'm going out to buy a Windows 7 phone". After hearing GeoHot say this, Brandon Watson, Director of Developer Experience for Windows Phone 7 posted the following on his Twitter account: "#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."
GeoHot could be just the thing Microsoft need to really push them up the mountain of mobile phone glory against Apple and Google. With a much more easy going attitude Microsoft could really swing things around from here on out.
