My 3G s has the yellow tint, as well as a very distorted speaker and GPS that is at least 6 or 7 miles of at all times. I ordered my phone from Apple, but the Apple store near me is out of stock. I have a Best Buy right near me, would I be able to get an exchange at Best Buy and AT&T stores as well as Apple? Or is it just the Apple store since I bought it from them? Thanks.
