I ordered 2 IPs 5 S on early Friday (10 minutes after midnight) on opening day which we received on Monday. My wife is not too happy with her new Gold/Silver 5 S for various reasons that I won't go into here. She's thinking of going back to her IP4 S. Her phone is the 2nd on our shared plan ($10 for the phone and $15 for her data). Rather than returning it, I'm thinking of selling it on eBay. The phone was a full upgrade at ($199). I'm wondering if I'm looking for static from ATT/Apple if I were to do this. Effectively, I would be on the cuff for 24 months for this phone, but the monthly price should still be $25 plus tax whether she uses the 4 S or the 5 S. Anyone know what my downside would be if I were to sell the 5S on eBay? If I were to return it, my wife's free upgrade would be put back in place for possible upgrade to the IP6 whenever it come out (Fall of '14?).
