Combining the just-released "SMS GV Extension"(on Cydia) and a previous post by "ohaithar" on another site (who might be b777forever here since he uses the same avatar), you can now use the Native SMS app on your iPod touch and it will work to send and RECEIVE messages! Receiving doesn't seem to work (due to no notifications on GV), but I don't really care. I own GV Mobile + already. It's just really cool. Edit: Receiving works! Thanks to everyone who figured it out here!
