Blackberry is supported with the Javascript API 2.2 release:
At 2.2 the API supports the new Blackberry Torch (6.0) native browser. Key widgets such as the zoom slider, time slider, and geometric editing tools now work better on touch screen devices. Several new samples that use mobile frameworks like jQuery Mobile and dojox.mobile were added to the help along with a new mobile site where you can explore the samples and code gallery on your iOS, Android, or Blackberry Torch smart phone.
Hi Chris, I have tested the samples that are in mobile site (http://help.arcgis.com/EN/webapi/javascript/arcgis/mobile/index.html) but with no success. I have used the blackberry 9800 torch v6.0.0.227 simulator that come with the webworks plug-in for visual studio. All html controls are shown but no the map (see image attached). why does not it load the map? Is there something that I am forgeting to do?
