I recently spent some time debugging AJAX connections for a application I built for a client using Blackberry WebWorks (via PhoneGap) and jQuery Mobile. The app was already working great on iOS and Android, however my AJAX (XMLHTTPRequest's) were not working on Blackberry.

The blackberry playbook simulator doesn't yet include the web browser application, but I found it pretty easy to write my own using the qnx.media.QNXStageWebView class and calling the loadUrl method.

I downloaded the SDK and Simulator for the Blackberry Playbook today. A few quick notes about my experiences so far.

The first thing you should know if you are on a Mac is that you must have VMWare Fusion in order to run the Simulator at this time.
