I have serious proximity issues. I haven't tried the latest update yet so I'll give it a serious chance, but afterwards if it's still a problem can I exchange it? I don't want to do it in store cuz the people that work there... well... I've seen horror stories here to say the least and my experience has been less than satisfactory. I would want to do it by phone. Will they send a new (or refurb new) one to me and then I can send the old one back? If they send a refurbished unit, is it basically new? Is the case/glass new? I don't want something someone else has "used" basically. I don't care if the circuitry inside is refurbished, probably a good thing, but I want a new case. Will I be able to easily restore the phone back to exactly the way it was by just syncing it with iTunes? Or do I have to reinstall every single app etc..
