Javascript library for BlackBerry

I'm currently starting in the web mobile development along with come trench brothers. I've done some things for iPhone and Android using jQuery and JQTouch. Recently we've been playing with the idea to also support BlackBerry devices to an application we are developing (which promises a lot of rework). Our initial tests with the BlackBerry simulators were a disaster... practically nothing works as expected (styles, jQuery ui components, etc..). So we believe jQtouch ended not being the silver bullet for this job (wierd huh? =P ).

We are now looking for a jQtouch-like library for BlackBerry's older models (Bold, Curve, Storm, Storm开发者_如何学Python2... Torch has a Webkit implementation so it works like a charm).

Any ideas?

Update: ----

Im currently working with XUI which is the only option I have found for OS4.6 and 5. Its really light weight and wraps up some issues nicely. I'm only concerned on the poor documentation it has and the fact that there are almost no extensions/plugins so you basically need to create the UI components you require from scratch (which sucks big time).

None exist for the older OS before 6.0.

Only basic Javascript and CSS work, like version 2.0.

The old browser was terrible, more like IE(I would even say worst) you see my point.

jQuery mobile will probably support it in a near future : http://jquerymobile.com/gbs/

So, stick to basic mobile web site for the BlackBerry older than 6.0.
