FIRST: Buying from an AT&T store is the first mistake, I will NEVER buy at an AT&T store again. Poor customer service, lies, failed to acknowledge lack of coverage in my area. What is APPLE thinking making these guys the exclusive cellular vendor?
To address your concerns: *Yes, you can take it back to an APPLE store*. I returned mine on day 17, Apple gave me a new one. Still no cell service in my area. Best the AT&T store could offer: sell it on ebay, they (AT&T) refused to take it back, saying is is a steadfast Apple policy not to return a phone after 14 days. Apple store manager just shook his head in digust when I conveyed that to him, and said they should have taken it back with a 10% restocking fee.
Will be returning my iphone AGAIN and exchanging it for a touch ipod. All the features except cellular, and I save $59.00
+ for AT&T service.
PS - Virginia Beach residents: AVOID THE HILLTOP STORE - THEY ARE LIARS!
NO SERVICE inside buildings, or just about anywhere on Shore Drive
