I have two iPhone 4s's for sale. Both are 16Gb. Both include chargers.
And I think I may still have the original boxes as well.
The black one has been in the Otter case since day one and is pretty much 9.9/10 in condition. It is unlocked, but was on AT&T. It will ship in the Otter case.
The white one is 9/10 and is currently still locked to AT&T, but I can have it unlocked in a few days (they have a 14 days lockout period after you upgrade phones).
Price is $190 each OBO
shipped CONUS, on Ebay 16Gb unlocked 4s's go for $205 to $250.
I take Paypal
