Microsoft is dictating the hardware that WinMo/Phone/Series 7 can run on, and (I'm not sure if this is rumor or confirmed) it looks like a capacitive screen will be required.
Now, if that's the case, someone might be able to hack it onto a TP2 or something like that, but it seems as though the most likely candidate for an upgrade to WinPhone 7 is the HD2.
Microsoft was able to keep something like WP7S quiet for soooooo long, I HIGHLY doubt they would have a hard time keeping their software on lock.
I think your wrong, I just want to know when the OS will be given to developers as that is when it will leak, if you listened to Steve Balmer right at the start he says they are announcing WP7 before the leaks occur.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
