Hi, I've switched from the iPhone to the Hero a week ago. I really like the Hero, even though some functions are better on the iphone (like the musci player). There is one Issue however, which is really bugging me with the HTC, which might make me switch back to the iPHone if I can't find a solution. Problem: When I call with my headset (Not the original ones, I don't have huge ear holes....) I can't "switch off" the screen and put the phone in my pocket and call while walking... This sucks, as I have to hold the phone in my hands, which kind of kills the idea of having a headset. Does anyone have the same Issue?
