Hey, since they are offering a 30 day money back guarantee why don't you just keep it for the 30 days and return it. No restocking charge, and they let you off of AT&T's contract.
Good idea! I might try it for the H*** of it! I want to see what I am missing..or not missing. LOL
It isn't 100% though and appears to be "standard":
For the 30-day, risk-free trial, if you are not completely satisfied you can return your undamaged phone for a refund in the first 30-days and pay only for airtime and usage charges; prorated monthly service charges apply.
