Merged improvements from newer forks of fruitstrap fruitstrap

Install and debug iPhone apps without using Xcode. Designed to work on unjailbroken devices.

Requirements

fruitstrap [-q/--quiet] [-t/--timeout timeout(seconds)] [-v/--verbose] <command> [<args>]

Commands available:

install [--id=device_id] --bundle=bundle.app [--debug] [--args=arguments]: Install the specified app with optional arguments to the specified device, or all attached devices if none are specified.
uninstall [--id=device_id] --bundle-id=<bundle id>: Removed the specified bundle identifier (eg com.foo.MyApp) from the specified device, or all attached devices if none are specified.
upload [--id=device_id] --bundle-id=<bundle id> --file=filename [--target=filename] Uploads a file to the documents directory of the app specified with the bundle identifier (eg com.foo.MyApp) to the specified device, or all attached devices if none are specified.
list-files [--id=device_id] --bundle-id=<bundle id> Lists the the files in the app-specific sandbox specified with the bundle identifier (eg com.foo.MyApp) on the specified device, or all attached devices if none are specified.
list-devices: List all attached devices.

The included demo.app represents the minimum required to get code running on iOS.
make install will install demo.app to the device.
make debug will install demo.app and launch a GDB session.

With some modifications, it may be possible to use this without Xcode installed; however, you would need a copy of the relevant DeveloperDiskImage.dmg (included with Xcode). GDB would also run slower as symbols would be downloaded from the device on-the-fly.

If the app is not compiled for the right iOS version, fruitstrap will succeed but the app will not run (eg. if your app is iOS 5+ only and the device is running iOS 4, fruitstrap runs and seems to copy the app to the device, but it does not appear in Springboard)
