if he's running HSDPA/GPRS/3G he's probably on a GSM network, so probably AT&T. Unforunately I have the Sprint version so I don't know how much this applies to you, but in my Touch Pro theres a icon in the settings that says "Update Profile." I had my internet crap out on me, but after I reprovisioned it, it was fine. Theres a ## phone code to do this over the air, but since I don't use AT&T I don't know what it is. If you can't find information on either, call up AT&T and ask them to reprovision your data for you.

I don't think HSDPA is rolled out in the states for phones yet, though I could be wrong. I think the AT&T touch pros use normal 3G, though again, I could be wrong. GPRS is the wicked old school data connection that the first gen iPhones used.
