Dev Team member MuscleNerd managed to send text messages from a jailbroken iPad 3G. According to MuscleNerd, The MobileSMS.app from the iPhone doesn’t run properly on the iPad so he had to use raw command lines via Terminal.
Since the AT&T plan that comes with the iPad 3G doesn’t allow to send SMS, MuscleNerd used a T-Mobile SIM card that he cut down into a MicroSIM.
This is just the beginning. I’m sure we’ll see more and more of these hacks
