Service without a post plan?

[n0m0n]

I just got a ATT referb and at this time I am on T-Mo until my contract runs out.
I want to try to get my 3g iPhone up and running on ATT without paying 70.00 for the iPhone plan.
Can I go with a prepaid, $1.00 a day, or go plan, and add the unlimited data for 20.00?
I know that I can go with a $15.00 voice prepaid and add the 20.00 data for a 2g or none iPhone IMEI but I was told that once the system recognizes tat its a iPhone it will shut me down.
Is this correct?
Is there a work around?

Thanks

It won't shut you down, it'll just bug you to get the plan if you don't have it and you'll get charged big time if you accidentally use 3G/EDGE without a plan, if you're asking what I think you're asking.

I thought since I would be adding the 20.00 unlimited data plan I would be covered if I use 3g or edge?

I was wondering if I could get away this just getting a GO or prepaid voice place and then attach the 20.00 data to that?

^Indeed. Also, EDGE is $20/month, 3G/EDGE is $30/month.
