From what I've read (and please correct me if Im wrong):
Phonegap claim that they started trying to make this but couldn't, so they passed it to the Apache Software Foundation.
Apache in their awesomeness (Long live Apache) fixed it, developed it, and made it supremely awesome.
Now Phonegap are trying to maintain and enhance a copy they took back, but keep stuffing it up.
So, by my thinking, I want a solid and trustworthy dev platform made by seasoned professionals that I can trust, rather than a patched upon sub-version of said. Therefore Id say I am a Cordova developer NOT a Phonegap developer.
Iv also read that in a second desperate attempt to gain popularity and control over the great works of Apache, Phonegap has now been sold under the Adobe flag. You know Adobe, they are the guys who do nothing for free and are so bad at maintaining software life-cycles that their apps need to perform updates every time you blink, and for some reason each of their apps are about 100 times the size you would expect.
I guess that is the summary of my research if I didn't read it wrongly.
And if true, then lets all drop this whole Phonegap nonsense and just stick with Cordova.
