Hello, last night my iphone started acting wierd, no sound is working at all, the speaker is not working, and when i call someone when i hit the "loudspeaker" button, it does not stay lit...? Its very wierd and when i put the phone up to my ear, its supposed to go black, well it doesn't... And my battery life is horrible??? after 4 hours of leaving the phone left asleep, it went to less than half battery life. i opened up itunes, and restored my phone and installed the newest firmware, no luck? I don't know what to do... also it doesnt say the headphones are plugged in or anything
