iNdependence is a Cocoa-based application for Mac OS X which provides an easy-to-use interface for jailbreak, activation, SSH installation, and ringtone/wallpaper/application installation on your iPhone. It's open source under the GNU v2 license.

iNdependence's source code for interacting with the iPhone has been broken out into a library (libPhoneInteraction), this way being more easily reusable by other applications.

Platforms and configurations known to work with iNdependence:
· Intel Mac, Mac OS X 10.4.10 - Firmware 1.0, 1.0.1, 1.0.2 - iTunes 7.3 to 7.4.1
· PPC Mac, Mac OS X 10.4.10 - Firmware 1.0, 1.0.1, 1.0.2 - iTunes 7.3 to 7.4.1

NOTES:
· This program does not work with the iPod Touch
· This program will not perform a SIM unlock. However, it will activate your phone with any type of SIM card.
· Starting with version 1.1.1 (and higher), iNdepdendence has been updated to work with iTunes 7.4. Do not use previous versions of iNdependence with iTunes 7.4 as it (in combination with a bad iTunes restore) could cause your phone to endlessly reboot!
· Please see the README file with it before you do anything else. In order to run it, you must first copy the MobileDevice library from iTunes 7.4.2 into the application bundle using the iNdependence MobDev Tool. Instructions for this are in the README file. This allows you to have any version of iTunes installed and not worry about breaking iNdependence. The major feature for this release is the MeCCA patch to enable custom ringtones to be placed in the system ringtones directory on the phone.
