I was using my phone all day just fine and around 8:30 tonight i tried sending a text and it wouldnt work, tried resending it, wouldnt work, tried making a phone call wouldnt work, tried going online wouldnt work. Its been 2 hours and still nothing, took out the battery a few times, SD card. I finnally hard reset it to factory settings. Now the problem is i cant call to activate it because it will not make phone calls. It says i have service. Im super frustrated because i need to call someone and this is the only phone i have. It worked fine before 2.2 came out which by the way i dont think did any benefit. please help!
