Research in Motion’s 4G BlackBerry PlayBook is now certified to fly on the airwaves. Bla1ze noticed one model of it hitting the PTCRB database listing OS 188.8.131.528 as the OS at certification. There is no release date which RIM has also been coy about so far. I am really curious to see what RIM has planned for the 4G PlayBook rollout. I know there are enterprises that are waiting for them and carriers like Verizon are almost definitely carrying them. My big questions are when and for how much.
