What is the Blackberry PlayBook's user agent?

What is the User-Agent string for the Blackbe开发者_开发百科rry PlayBook's web browser?

OS 1.0 - According to RIM it's

Mozilla/5.0 (PlayBook; U; RIM Tablet OS 1.0.0; en-US) AppleWebKit/534.8+
(KHTML, like Gecko) Version/0.0.1 Safari/534.8+

OS 2.0.0

Mozilla/5.0 (PlayBook; U; RIM Tablet OS 2.0.0; en-US) AppleWebKit/535.1+ (KHTML, like Gecko) Version/7.2.0.0 Safari/535.1+

OS 2.0.1

Mozilla/5.0 (PlayBook; U; RIM Tablet OS 2.0.1; en-US) AppleWebKit/535.8+ (KHTML, like Gecko) Version/7.2.0.1 Safari/535.8+

OS 2.1.0

Mozilla/5.0 (PlayBook; U; RIM Tablet OS 2.1.0; en-US) AppleWebKit/536.2+ (KHTML, like Gecko) Version/7.2.1.0 Safari/536.2+

FWIW, the one for my Playbook (retail) at OS 1.0.1.1690 is

Mozilla/5.0 (PlayBook; U; RIM Tablet OS 1.0.0; en-US) AppleWebKit/534.8+ (KHTML, like Gecko) Version/0.0.1 Safari/534.8+.

The user-agent string from the SDK browser, which is not final or official in any way, looks like this:

mozilla/5.0 (x11; u; linux i686; en-us) applewebkit/534.0 (khtml, like gecko)

My Playbook is running OS 2.0.1.358, and the User-Agent is:

Mozilla/5.0 (PlayBook; U; RIM Tablet OS 2.0.1; en-US) AppleWebKit/535.8+ (KHTML, like Gecko) Version/7.2.0.1 Safari/535.8+
