Sell your old iPhone for as much as $192!
Got an iPhone 3G or original iPhone that you’d like to sell to pay for your upgrade to the iPhone 3G S? Guess what, YOU CAN!
I ran some quotes just now at Gazelle and found that you can sell your iPhone 3G for as much as $192 (the 16GB iPhone 3G S is only $199 for valid upgrades).
Gazelle will even give you as much as $110 for the original iPhone, which would more than pay for the iPhone 3G since the price has dropped to $99 with the release of the new iPhone 3G S.
This means that right now, as an AT&T customer, you could sell your current iPhone and upgrade to the 3G or 3G S for little or no cost! You may even make a buck in the process!
