For most people SMS's cost 10 cents to send and 10 cents to receive SMS's. I would think that since the iPhone is a virtual full fledged computer that we may be able to find a way to create a public SMS gateway atleast for sending SMS's rather than using the providors pay as you go gateway.

The idea would be to create an iphone application that utilizes this public gateway to at least send outgoing SMS's thus bypassing the service providers expensive one. This could help cut costs for total sms'ing by half.

Anyone up for this idea?
