I was looking to see if this was possible on google. An old thread came up..but I was wondering: since we can jailbreak the phone and transfer internet (3g) data to our computers through USB/Bluetooth...why can't we send data back to the phone to send a text message through it? I know you can get the iphone explorer but that thing lags and is pretty crappy in general. Is it possible for there to be some sort of client that you could have on your computer, that when your phone was in bluetooth range you could reply to texts on the computer? This would be an amazing feature that I think a lot of people would pay for.
