I did the hack, and can send out pictures just fine, It doesn't seem to recieve them though, still playing around with it though.
I had to put the sim card in another non-iphone, and it took a few tries to get a pic to send out. then when it finally went, I put the card back in my iphone, and it worked fine sending out.
Do I need to put the sim card back in the non-iphone, and receive a few pics also to get that to work? or should everything work all at once??
UPDATE - I received a picture, looks great. But after trying a few more times, it doesn't seem to work all the time. It hangs up, and get the little red exclamation marks, saying the pic won't go thru. Not sure if it is going to work very well or not right now.
