iphone with AT&T, pay as you go(go phone)

[lostngone]

Ok I upgraded to a iPhone 3G so I was looking for thinks to do with my original iPhone.

I jail-broke/unlocked it and went to AT&T and picked up a pay as you go SIM.

Everything is working but I keep getting billed for "GPRS" fees anywhere from .01 cents to a dollar, 5 or 6 times an hour even if I am not using it. I am guessing this has to do with voice mail?

Is this correct, or is it something else making the GPRS connection. How can I stop the phone from doing this?

You can either make a custom configuration profile yourself with Apple's tool or go to http://www.unlockit.co.nz/ on your iPhone. To re-enable cellular data, just remove the profile.
