You know the BlackBerry PlayBook that we caught sight of at CES earlier a couple of weeks ago? While it does look pretty good on paper, there are plenty of naysayers in the market since the device hasn’t been proven just yet – which is fair, to say the least. Well, little birds have been chirping on how RIM (Research In Motion) are working on a version of the BlackBerry PlayBook which will be compatible with AT&T’s 3G cellular data networks, hitting the markets later this March at best, or in early April. Not only that, a LTE version is also cited to hit the market once the 3G model gets off the mark, making us pretty interested in seeing which particular model will sell better. Should there be a huge number of uptake on AT&T’s PlayBook (3G and LTE versions), we do hope that AT&T’s network is able to handle all the additional data requests and traffic. Of course, if you’re rocking to Sprint, you know you have some PlayBook goodness coming your way eventually as well.
