A friend of mine bought an iphone and doesnt like it. She wants to go back to a blackberry. So she said he was taking it back to AT&T and return it to get the blackberry since she's in her first 30 days. She offered to sell it to me for what she paid for it - $200. To me this seems like a perfect deal. I get everything that came with it plus a case and car charger. But, will she have to pay any extra costs due to not returning the iphone? She'll have to pay for the data plan anyway for the blackberry wont she? Basically, can I buy this and still have a non-guilty conscience?
