Here’s a tip from Ami at Cool Hunting: Capitalizing on the loophole that lets most mobile users out of unwanted or unneeded contracts by transferring them to someone else, a new online service called Cellswapper allows cell users who want to abandon their current cellular plan to offer it on the new site it to others looking to pick up a short-term plan. To provide the win-win exchange (neither party has to pay a fee for starting or canceling service) Cellswapper uses a Transfer Tracking system to keep users informed about the exchange and helps facilitate the legal transfer. For users hoping to ditch non-Cingular contracts in order to sign up for a multi-year exclusive deal with Cingular for the recently announced Apple iPhone , Cellswapper may be a viable solution.
