Thanks to the latest developer beta OS for the Playbook that has been rolled out today, bundled AT&T apps were spotted, thus suggesting that AT&T could be one of the carriers to support RIM’s 4G LTE Blackberry Playbook. It should also be noted that Verizon is another possibility as the Verizon Wireless store tab made a brief appearance in the App World in the past. In any case this isn’t a confirmation but if you are looking forward to the 4G Playbook, then perhaps you might want to keep an eye on both these carriers. Until then be sure to check back with us for more updates.
