I can't finda jQuery mobile(phonegap) or jQuery mobile with theme(phonegap) on my adobe DW cs6 [ New Document>Page from samples>mobile starters ] ??
I have the same problem.
But I don't know if these contain what you're looking for nor do I know how to make dreamweaver see it.
This has been changed in CS6 version. The one your looking for with (phonegap) is now the third one on the list jQuery Mobile with theme (Local).
Here is the link that explains: http://tv.adobe.com/watch/learn-dreamweaver-cs6/enhanced-jquery-mobile -support/
Hope this helps!
