Hi tuner1406, just to sum up what everyone is saying, is that you do need some type of data connection to send data from point A to point B. There are no free 3G networks as far as any of us are aware and hacking AT&T's network would be stealing, which we do not endorse in these forums and which I am sure when you look at it in the sense of stealing, you might not want to do it either due to the moral and ethical concerns.
Sorry about the "tone" in this thread. Sometimes we get people that are just trying to game the system and are malicious and other times we get people that really do not know and understand how things work which sounds like you might be in that camp. The first type of person is frustrating, the second type sometimes gets the frustration from the first type.
Again sorry about the tone of the thread and we hope you have lots more questions that we can help you with!
Cheers!
