Requirements:

• capistrano (ruby gem)
• dpkg

to build the iphone app: cap build

to build the .deb package (for easy installation on your device): cap package

Note: there's still an issue with code signing. in order to run the iphone app, you need to run the 'GRiS" executable through ldid -S. This tool is available for your iphone via apt-get install ldid. I cannot find a version for linux/OSX. See here for more details: http://www.saurik.com/id/8

The package cap task automatically tries to do this. This means you'll need to setup your device login / hostname details in capistrano.

if you have setup your device with capistrano, you should also be able to do cap package:install to actually install the built version of the app.
