So my brother told me that one of his friends said there is an app that lets you text a cell phone and choose what you want the callback number to be. I think he said it was a 3rd party app that jailbroken iphones/ipod touches can run. Is there an app that is really like this? It would be fun to use to prank people with haha. Sorry for the topic title, I wanted to search for "jailbroken text" but accidentally made it the name of the topic.
