Alltel Data not Working...

[OrionSX]

Hi guys, I'm having an issue where I can't connect to 1xRTT data networks. I haven't tried in an EV-DO network as I live about 20 miles from the nearest one, but I didn't have this problem until after I flashed Psyki 3. After I noticed the issue I tried flashing a WM6.5 ROM, and had the same problem. Is there some Alltel CAB I need to install? Phone and SMS work just fine, just can't establish a data connection. I get either a "Cannot connect for some unknown reason..." or a "Your username and password is wrong..." message. I've tried hard-resetting immediately after the flash, and soft-resetting as well. Alltel doesn't have automated data provisioning that I know of... Any help would be greatly appreciated!
