WiFi Greyed out iOS 6.1.3
To start, I bought this phone from my company. (We fix most phones and computers.) The whole phone worked up until 7/6/13 when I couldn't see any WiFi connections around me. Normally I see at least 6. I powered my phone off, turned it back on and now my WiFi won't turn on at all. I can still see my WiFi Address, I've tried back up and restarting and wiping and all that jazz. Nothing out of it. I did try the freezer trick for about 15 minutes and it worked for about 2 hours.
I haven't had the chance to open the phone to look, I've been away on vacation, but from what people say it sounds like faulty soldering on the WiFi chip near the head phone jack. Can anyone tell me how to check if it's the solder? I have no experience with soldering so I wouldn't know where to start. I heard about the heat gun trick. Should I try it?
