So my iPhone 4 that I got on release day stopped working (I posted this weekend about it- I couldn't hear callers, didn't seem to be the normal headphone bug, etc). I brought it to the apple store and they replaced it. I was sitting here doing some school work and I heard my phone vibrate (I always have it on vibrate) I picked it up and it wont turn on. OK, maybe it died but I didn't remember it being low on battery... so I got my charger, plugged it in, nothing. iTunes doesn't even see a phone being plugged into the computer. Will NOT turn on... I'm not sure if there even is anything I can try (other than throwing it out the fricken window I'm sooo frustrated right now...) any suggestions??
