Trading into a Note 2 tomorrow... coming from an iPhone 5. Looking forward to learning new things and attempting to keep since things are so different from iOS. My question.... the trade is going down @ an AT&T company store so both phones can be checked for validity. What should I specifically & the rep. look @ w/ the Note 2? So that I'll know this Note 2 is legit, not stolen and won't get blacklisted. Thanks everyone!!
