This works but can result in a Dr. Skipped Firstuse profile.

Then run the webOS Doctor. Now you should be able to sign in using the data service on your Bell plan, and you'll get rid of any potential profile issues.
You can use impostah to 'fix' profile issues and get rid of the Dr. Skipped Firstuse profile, and get paid app catalog access. However, after doing this on 2 AT&T Veer's, I notice that there is something funny going on with the Palm Profile (doesn't show up in Accounts), and backups don't work. So, I'd recommend doctoring like I mentioned above.
