Nope all running XP. I have always used it on my laptop but now it doesn't show in the wireless section. Have tried to reboot 3 times. I don;t want to reflash my phone just to find out T-Mobile are blocking something or another... I find it rather coincidental that I can no longer vnc into my home machine nore can I use mobile hotspot By the way, the app seems to work ok just that I can't see the wireless connection in windows.
