Okay so my phone's screen went blank for a few days and then when it came back on the wifi, bluetooth and carrier didn't work (the switch for wifi is greyed out) it's been about a week now and i've tried everything, I've reset the network setting, restarted it countless times, restored it on itunes to the original factory setting. I've done everything and it still wont work. I can't send it back to apple because my warranty is up and they said they wont replace it and I got this phone just over a year ago and I'm on a 3 year plan which I cant afford to pay off and buy a whole new phone because I'm only 15. Can someone please help me with this?! p.s. i don't know if it's the newer iOS 6 that's causing it to do this because i updated my phone after it turned back on and the wifi didnt work even before the update.
