I have a white iPhone 4S, i got it october 14, never dropped it, had a case on it since day 1, minute 1. And starting today, i noticed my battery life would literally go down by the minute, i unplugged it, and within 3 minutes it was down to 99%, and I went out today, and I would recieve an imessage or text message, and i would loose service at that time. it would say searching... searching... and then I would get it back but every 3ish minutes i loose service unless im in my wifi area. I have at&t, i know sprint was having problems with their service but i havent heard of anything about this with at&t, it really frustrates me. I realllly need an answer on how to fix this, please let me know!! thanks!
