In the latest developer beta OS for the PlayBook that released today, user were greeted with bundled AT&T apps. Could this be a sign that AT&T will be one of the US carriers to offer the 4G LTE BlackBerry PlayBook?

We have even seen a similar tell-tale sign for Verizon Wireless, when the ability to manage your Verizon Wireless store tab accidentally popped up in App World. Nonetheless, there hasn’t been any word on when or even if these top carriers will offer the 4G PlayBook, but some of the signs are there.

What carriers do you think will offer the 4G PlayBook in the US? Sound off in the comments!

Thanks Cam!
