so my phone was purchased back in the middle of sept. no problems. today the phone worked fine and then around 5pm, the phone would not turn on. the batter was full, i have not jail broken the phone. when i got home, i pulled it into the wall and tried the power... nothing happened. then connected it to the macbook pro and itunes picked up on it and backed it up but still nothing from the 3g. the phone was not damaged or dropped. tried holding down the power and home button for more than 10 secs... nothing.... what gives? tried googling it, but no avail. please help!
