My sony ericsson w995 has some problem. I was watching videos on youtube and suddenly in the middle of a video it auto shut down it self. I can on it but when it reaches the wall paper page (the main page?) The part where it was supposed to write the mobile network's name kept writing "Searching" and when the screen off-s itself (like normally when you don't hit any keypad and the screen turns blank), I couldn't press anything to on it because nothing works. Now it's forever restarting itself then to the wall paper page with "Searching" on the top and then to offing the screen and it keeps repeating. Hitting the keys does not work. please help ASAP?
