So since RIM released the devbeta for OS2 I've registered my Playbook's PIN on their website a grand total of five times (waiting at least an hour between each of course) and so far I have not received any download notification on my PB. I have repeatedly (and repeatedly, and repeatedly...) checked for updates from my PB's menu as well as from the BB Desktop Manager. NOTHING. Does anybody have any idea why this may be and what I can do?
