Great buy on a nice phone.

If you're lucky, an AT&T representative can just wave their magic wand and remove the suspension, but they also want to get a proof of purchase receipt from the seller showing that the phone was legally purchased from Best Buy

AT&T told me that when they looked up the IMEI number of this new phone, it was still registered as INVENTORY AT BEST BUY

Bad buy.

I had the same issue as many others who purchased this: the phone was still listed as Best Buy

AT&T said the phone is originally from Best Buy but was not activated properly at purchase so they cannot allow it on their network.
