With the Verizon iPhone 4 dropping in a few weeks and rumors already swirling about the iPhone 5, it is time to get rid of that iPhone 3GS that you are still toting around. I understand there might be early termination fees, but your old iPhone can get you the cash to cover them. And if you are lucky enough to not have an early termination fee, your old iPhone can take a big chunk off the new iPhone 5 price tag.

Boston is home to three recommerce sites just dying to get you paid for your old iPhone: Gazelle, YouRenew & NextWorth. And they really want your old phones; so much so, that NextWorth went so far as to issue a press release this morning detailing how much money that want to give you.

All three companies offer free shipping, but NextWorth goes a step further and allows you to instantly upgrade to an iPhone 4 at Target stores. You can also receive pre-paid Target cards.

Here are the current values for your iPhone 3G and 3GS:

NextWorth:

• iPhone 3GS 32GB – $201
• iPhone 3GS 16GB – $155
• iPhone 3G 16GB – $125

Gazelle:
