The problem is, AT&T doesn't want the iPhones on their network without a data plan. I have heard of one or two people using a iPhone without a data plan, but they had to convince AT&T that they would never use data on the phone except for WiFi. I do believe that AT&T made an exception for them based on their certain condition of the cellular network in their area.

I was told when I bought my 3GS that AT&T is now performing sweeps on a regular basis and finding the iPhones on their network that do not have data plans, and notifying the users as you have been notified. It is their network and their rules. People like myself pay for the data plan because I use it a lot. More so than my Blackberry plan when I had it.

As for going to T-Mobile, there was an article out in the past few weeks that stated that T-Mobile was possibly starting to take people off of the Sidekick plans that were being used with unlocked iPhones. The plan included messaging and internet for $1 a day, as they put it. Now, I guess they are going to try and split the messaging and internet to make some more money off of the AT&T users who jump ship. Their network, their rules.

Besides, you'd be amazed at how much one of these phones can go through data, even without ever starting the safari browser. So many apps use the internet for their content that it even amazes me how I can rack up so much data usage, and not even pay attention to the fact that I am doing it. I feel the data plan is justified for the phone, to fully utilize the device to it's full potential.
