It seems by all accounts Gazelle.com is a trouble-free way to sell your old iPhone. Sure you can get more on ebay or craigslist, but gazelle makes it so easy that it may be worth it for some. They offered me $123 for my iPhone 3G 8GB. I have to send it back within the next few days or the offer expires. As it was unlocked/jailbroken, I could have gotten something more elsewhere, but there is a glut of these on the market now, so I just want to sell it fast. Anyway, here is the question for those who have used this service. Did Gazelle pay you what they promised or did they find a way to reduce their offer after they received your iPhone, claiming it isn't in the condition you reported? Thanks.
