PdaNet claims to mask tethering from AT&T. You could try that app.
In my experience, 3G->WiFi tethering under AT&T is pretty awful. Unless you're in an ideal location, it's painfully slow and there are frequent timeouts while web browsing and checking email.
This has been my experience while attempting to use a MBP to connect to the 'net via iPhone. An iPad will be less demanding of bandwidth than a Mac so it may not have the same trouble.
