I have a leather wallet style case for my iPhone, which wraps around to protect the screen. (It's designed for an iPhone.)I've also had massive freeze/lock up issues with the phone. Any connection? thx.
I'm going to have to say no... a big loud no at that. Is the case a brand name case? Meaning you didn't buy a case that has say ... a large magnet on the back of it, or anything other than normal case materials, right?
You try a Restore on your iPhone. That usually fixes any issues. Restore your iPhone
Oh yeah... it's not Jailbroken or otherwise hacked, is it?
