ok so here's the deal. About a month ago I ordered a refurb iphone 4 for my wife. att was out of stock on the refurbs and i thought the order was cancelled. about a week ago, i ordered a brand new iphone 4 and was charged the discounted upgrade price. i looked at my credit card bill and notice that i was charged for both the new iphone 4 and the refurb. I called att and sure enough, they have shipped the refurb as well...so basically i have 1 new and 1 refurb both at discounted prices. my question is what do i do with the refurb? can i get another sim card from the att store and have it programmed with another number on my account? or should i just send the refurb back?
