Hello,
This is really more a phonegap question than a Concrete5 question.
C5 is a set of php scripts. Phonegap uses javascript and so can interact with any php script.

The how is a phonegap question.

Actually I reckon this is still a concrete5 related question, as it's sort of asking if concrete5 has any REST/JSON/whatever interfaces available for performing tasks like authentication.

I've actually had a similar sort of thought before, to create an app (but a desktop one) that handles the resizing and uploading of images in bulk. I realied it would be pretty tricky though as there's no (to my knowledge) way to perform such tasks without using the web interface.

I can envisage some nice ways to get some data _from_ a concrete5 site to a phone app (using JSON, etc), but I'd be keen to hear from others about interacting with a site in more complex ways.

I know Mr Strat has released this -https://github.com/goradiantweb/radiantweb_api...
But I've not explored it myself.

That GitHub project from Mr Strat looks really interesting, thanks for pointing me in that direction mesuva. I'll have to take a closer look at it.

@Mesuva Yes indeed you're right, I forgot he needed at least a tool or a model to bridge between the js and C5 helpers.

On a totally different topic, Mesuva I love your blog. Really one of the best ones for C5
