Wifi greyed, cell service showing "e", and phone getting really hot
So I restarted my phone and now the wifi is greyed out, when I turn 4g on it shows "e" , and my phone keeps getting really hot. I've tried restoring it, resetting the network settings, and pretty much everything else. What can I do other than take it to an apple store? My warranty is long gone and I can't buy a new phone.
