Data Roaming?

[eff3ctz]

I just purchased an iPhone, and am going to put the PrePaid Sidekick plan on it. I heard/saw that you have to turn Data Roaming on in order for it to work.
I currently live in Jacksonville, FL...when I take a vacation to Orange Beach, AL .. .will I be charged extra for data roaming?

Thanks.

I don't think so as long as you're still in the country and under T-Mobile's service.

Ok, thank you very much.
