As of yesterday, the Wikipedia mobile app is now available for download in
Blackberry AppWorld for the Playbook tablet:
https://appworld.blackberry.com/webstore/content/105171/
For this initial release we've disabled the 'saved pages' functionality,
but it should come back in a future release (saving/loading code should
become more consistent after the API usage merges). GPS functionality for
'nearby' articles works fine.
Big thanks to the guys at RIM for submitting an appropriate build system
and for helping with the review process!
In theory we should be able to port to recentish Blackberry handsets as
well using the appropriate variant of the WebWorks SDK, so stay tuned!
