Anytime you get a phone off of a 3rd party site like that, be very careful. If possible grab the ESN or other identifier for it, call the carrier and make sure you dont get a nice happy past due/collection balance tied in with that phone. I see it all the time working in support.
A refurb phone from att only has a 90 day warenty. If you can cancel your upgrade I would. Then goto a different site like letstalk.com and upgrade there. I got my 8900 for $1.00
