Try the AT&T build.prop/APN file found here:
However, be aware that when I flashed that file over Hyperdrive 17.1, it interfered with Hyperdrive Tweaks (which would then force close when trying to open). I'm not sure if the dev has fixed that problem... I moved on to a different ROM because at the time there wasn't a known solution I could find to the "+ being added to incoming/outgoing calls" issue (app Prefixer seems to be the solution most commonly mentioned, now).
I encountered the same problems with downloading apps based on the phone identification that you are seeing, and I did change one build.prop item manually (I forget which one), but it wasn't enough to get the store to properly recognize the phone. I think there are a few of them that need to be changed, and I didn't invest time to figure it out.
You will probably fix it if you go through the ATT build.prop file line by line and adjust on your phone just the items that refer to phone model ID... that would probably not break Hyperdrive Tweaks.
