It also really depends on who is assisting you. The Apple store has strict rules when it comes to them giving you another phone for a return from a defective iPhone. Hopefully they'll be able to fix your iPhone 4, depending on if you are still under your warranty.
Oh I could've gotten the iPhone 4s I may go next month and get it for 188? Anyways the guy said volume is fine well it's NOT what it wAS its drivin me crazy and no my hearing not worse the phone itself the grill is a little bent he said (where u hear from) soo that's the problem:-(
