As mentioned a few weeks ago, I've been looking at trade prices for my gf's 64GB 4S. Why is everyone using Gazelle? GameStop has a better deal. $399 credit or $319 cash. Gazelle - a mere $266. http://www.gamestop.com/recommerce/...le=Apple+iPhone+4S+64GB+AT&T+-+A1387&concept= http://www.gazelle.com/iphone/iphone-4s/at-t/iphone-4s-64gb-at-t-or-unlocked/480695-gpid Plus I dont have to send in the phone. No Brainer?
