Hi all, 3G signal appears and so does wifi but connectivity is acting stange and bad, mostly gone. Tried network reset as well as hard reset but doesn't work. I can't even turn off the find my phone or anything else that has to do with the network. In this state i won't even be able to download and update the next beta!! Couldn't switch back to 7.1.1 getting and error on itunes. Trying new install from a recovery mode just now. Any other advice? Or how to force a return to 7?
