First off, the OS does not contain carrier-specific settings.
The service books configure your BB for your carrier. If you're having MMS/Internet issues then your problem is not the OS but elsewhere as already stated.
Do you have a Blackberry data plan? You can't receive the service books without one.

...and I rarely use at&t OS's with my at&t BB's (unless at&t happens to have the latest OS for my models) and all my BB's work without any issues.
Again, the carrier branding of the OS is irrelevant.
