I plan on buying an iPhone 2g.

I really do not want to pay for that ripoff data plan that I'll end up not using so I heard that a good way to go about this was by putting an AT&T GoPhone sim in an iPhone thus to clear up costs.

Personally sounds good to me until I heard that AT&T stopped this practice and it is unable to be done anymore.

I have done research and unable to verify that there is a way around this. I have gotten older posts from when AT&T allowed it but not anything recent.

I'm pretty sure that an Unlocked & Jailbroken iPhone 2g will be able to use a AT&T GoPhone Sim Card, but I would just like yo verify it. Thank you for your time.
