Cellswapper is a new service launched today that lets you trade or sell your cellphone and contract, with no early termination fees.

It’s like celltradeusa, except it’s free to post. If your phone does get sold, you pay a $14.95 fee. Celltrade is free to post but you have to pay if you want to respond to inquiries, regardless of whether the phone gets sold.

A quick look shows only 82 plans and phones listed so far, so guess we’ll have to popularize Cellswapper enough for it to become useful.

If you’re looking to get out of your cellphone so you can jump over to Cingular’s junktruck network and get an iPhone, Cellswapper could be for you. — BEN POPKEN
