It looks like the 4G PlayBook is one step closer to being ready. Version 126.96.36.1998 is allegedly now rolling out for the few select lucky people that have the 4G PlayBook. I presume these folk are RIM and carrier employees only as sightings of the 4G PlayBook out in the wild are as rare as a Dodo. It was only a few days ago that we posted about the 4G PlayBook running OS version 188.8.131.525.
Needless to say, it looks like RIM is working hard to get things right. There is no mention of BBM being present, as a native app within this latest version so don't get too excited. And clearly you can't download this version to your WiFi PlayBook. Being in the UK my only concern (which is totally selfish) is where can I get some 4G's. We haven't got any here yet.
