Yesterday, we learned of RIM's offer to Android developers of a free BlackBerry PlayBook to anyone who submits an appby Feb. 13th but given the initial response to the app from other developers RIM has opened the offer up to everyone, no matter what type of app they wish to submit:
Wow BlackBerry Developer Community! You certainly weren’t shy about wanting in on the PlayBook offer for apps submitted to BlackBerry App World between now and February 13. And you know what? We are in the year of “Being Bold” and such an outpouring of interest from you should be rewarded! We’re opening this offer to any app – WebWorks, Native, AIR, and Android. Same deadline of February 13 applies. There are some terms and conditions, but they’re there to protect you and your content. We look forward to your submissions!
That sums it up, get your app in there and claim your free BlackBerry PlayBook. Just remember, you're going to have to follow the guidelines for submission and you can hit the source link for those full details.
