Be sure to video your encounter and take every piece of proof you can get that you gave it to someone at the store... A few years back, AT&T claimed they did not receive my phone back, but I had taken it to the local store where I watched them bag it up and take it away. Granted, I lost the receipt I was given, but I basically told the store manager I would not leave until it was fixed (and it almost closing time lol). Magically it got fixed.I dont if any one else is trading in an older iphone, but I called my local ATT store and asked for them to help with the trade in process, make sure all required information off, all settings factory, and shape of phone.. I have read that some traded ins were not done right and was discrepancy in what you turned in... they said be happy to help, just dont ask on release week heh.
on a side note, are our att phones coming from over seas, or will see shipping just from an att location Thanks
