My phone just randomly shut down yesterday night and rebooted and when it started back up it said preparing my sd card I didnt think anything of it...well the nxt morning when I woke up to my phone ringing with the standard us cellular ringtone. When I looked thru my phone everything but a few random pics were there I took it out and put it back in and now it says it damaged and nothing is there!! How the hell did this happen??? Is there anything I can do???
