I just got an iPhone with an extra upgrade to make a little extra money reselling. The only problem is I am having trouble selling it on Craigslist. It is just so overrun by scam posts. Also I'm pretty sure half of the people responding to me are trying to scam me. Are there any better forums or exchange sites you guys know of? Also, what do you think I should be trying to get for an ATT 16 Gig still sealed? Also, speaking of it still being sealed, is it a problem that it comes with a SIM card? Will they be able to activate it on my account? Thanks a lot for any tips you can lend!
