dude you dont even own a 2G what you bitching and moaning about. And what are you going to do if I prove my theory and it helps a lot of guys ?
Nobody has been able to crack this wi/fi problem about sometime somebody at least tried.
BTW if you delete prefrences.plist and rebot it is created clean.
You hook it your pC and even without runing itunes its being changed in the background.
This is one reason why you should stay far away from runing the latest itunes i.e. 8.x
