HELP! I have had this problem almost since the day I got the phone and it seems to be getting worse.I'll look up a web page (Wi-Fi or Edge) or be in Maps and the phone just returns to the home screen as if I hit the home button.The unit can just be sitting there loading the web page ----so I am not "accidentally" hitting the home button.Any help would be nice.Do I do a "hard start" ?.....This doesn't erase any of my contacts etc. does it?thanks Mike
