I am deciding between which library to use for development: jQuery Mobile or Sencha Touch. The application I am building will specifically target enterprise (Fortune 500) BlackBerries. The application will not require any hardware features, but the user experience/UI rendering should be as good as possible.
I am not familiar with BlackBerry OS adoption/upgrade statistics so I don't know what platform is my lowest common denominator. Are most enterprise users on BlackBerry 6+ or 5+ or 4+? I just don't know and I don't know where to find those statistics. What is your recommendation?
