Most tablets function just fine on their own, but RIM’s BlackBerry Playbook introduced a unique, yet restrictive interface that limits Bluetooth tethering to a similarly-branded handset. This feature, called BlackBerry Bridge , lets your tablet piggyback on a handset’s 3G data connection, also enabling access to productivity apps like email and calendar, which are still otherwise unavailable on the PlayBook. Unfortunately, this option hasn’t been made available for AT&T users, but that’s about to change, as the feature will be added to App World today . While the Bridge suite is totally gratis, enabling the AT&T 3G data connection requires a monthly tethering plan of $45, which means anyone grandfathered into the unlimited data feature will need to decide if it’s worth the jump. Bridge not sounding like your cup of tea? Don’t worry — at least you can take comfort in knowing that the days of pining for native email are numbered.
