The current gradeA() implementation evaluates to true in a lot of cases where the Device Support Grid says B or C support.  For example, according to Blackberry docs (http://docs.blackberry.com/en/developers/deliverables/11844/BB_Browser_content_support_by_version_438586_11.jsp) versio 4.7.1 and 5.0 of their browser support media queries fully and thus evaluate to true against the current gradeA() implementation.  However, BB 5 only has B-grade JQM support and 4.7.1 only has C-grade JQM support. 

 

Ideally, only the devices that show up as A-grade support on the Device Support Grid would return as true on the gradeA() function.  Not supplying this functionality as part of the framework requires each of us who are using JQM to check the Device Support Grid after each release and write our own custom device detection logic to match what is supported in the new version.  Please consider having a function in the framework that would accomplish this more accurately than gradeA() does today.
