Developer opera is announcing the release of the latest build of the iNdependence application. This Mac OS X app is based on the Cocoa application programming environment (API), and will provide users with a means of jailbreak activation, SSH installation, and ringtone/wallpaper/application installation on their iPhones. Here are the updates leading up to version 1.2.3:

•  Version 1.2.3:
• This version fixes a number of bugs in version 1.2.2, makes 1.1.1 activation a bit easier, and also adds the ability to have 3rd party applications show up in SpringBoard when using the 1.1.1 phone firmware. If you have previously used iNdependence version 1.2.2 to jailbreak/activate a 1.1.1 phone, and want to use 3rd party applications, use the included SpringBoardPatcher application.
• Version 1.2.2:
• This version works with phone firmware 1.1.1, although the activation/jailbreak process is a bit more complicated now. The documentation has been moved from the README file into the Help menu within the application itself, so please read through that before asking questions.
• Please note that if you have used anySIM or other free SIM unlocking solutions (anything except for the iPhoneSimFree solution), and you upgrade to 1.1.1, it will wipe out the SIM unlock and render the phone and text message part of your phone inoperable. Everything else will work though.
• Notes:
• This program does not work with the iPod Touch [You'll need iJailbreak for that]
  
• 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!
