Yet I'm still having this issue as well. my AT&T Next hasn't been reset and I got billed for the installment for the phone that I returned. I contacted AT&T to credit back the installment cost since I don't have the phone that I returned. So AT&T did credit me back and told me that I should wait 24-48 hours for AT&T Next to reset. Well it's been past 24-48 hours so looks like I'm going to the Apple store and get this sorted out (since I purchased at the Apple Store, Apple store is the one to reset my AT&T Next).
