Right now the best way around it is to backup and then wipe your EFS folder.
As already mentioned above, one of the members here contacted some AT&T execs and made them aware of the problem. AT&T discovered that when entering IMEI numbers for a certain 10" galaxy tab into their database, they messed one up, transposing 2 digits. This erroneous number range just so happened to coincide with a range of Galaxy Note IMEIs. That caused some Note owners to have their device identified as a 10" galaxy tab. They have since fixed the database error, so Notes are no longer being identified as tablets.
Whether or not the proper IMEIs for international Notes are in their system, I don't know. However, when I log onto my online account management, the system doesn't recognize my phone. It shows a generic flip phone. When I go to manage features, the only data options it gives me are the dumbphone data plans; $15 for unlimited. This leads me to believe that AT&T does NOT have the international Notes' IMEIs in their system. Sure, the system may somehow be capable of telling the rep that the phone model is reported as N-7000, but the system clearly doesn't "know" that it's a smartphone.
