The Bold is RIM’s first smartphone that supports AT&T’s Cellular Video service. Our buddy Troy over at BBNews got a hold on an intranet posting at AT&T pointing to some issues users might have if they upgrade to a Bold. If you are just buying a Bold and starting a new BlackBerry plan the Cellular Video should work fine. If you already had a BlackBerry plan provisioned on your account and upgraded to a Bold then you will run into an issue where it will tell you that a MediaNet plan is required.
All you have to do to fix it is have an AT&T Rep remove and re-add the BlackBerry plan to your account to fix it.
Thanks DavidB for sending this one in!
