Installer 4.0 Beta Leaked
August 5, 2008
While the RiP Dev Team, creators of Installer, have kept their blog quiet, versions of Installer 4.0 have begun to surface. This appears to be a very rough beta release.
The iPhone Dev Team, reporting that they had received an advance copy of Installer 4.0 over the weekend, said they estimated a public-release wouldn't be available within a few days, a definite takeaway that Installer 4.0 is not exactly ready for primetime.
If you'd like to proceed, however, you can try and snag a leaked copy from HERE or HERE or HERE.
You'll need SSH to install Installer 4.0, but don't worry, Nic's posted a full walkthrough on how to do this: How to SSH on the iPhone.
In a nutshell you'll need to extract the zip file, use SSH to get Installer.app into your /Applications folder, run 'chmod -R 777 /Applications/Installer.app' and 'chmod a+srx /Applications/Installer.app/Installer' via terminal, and restart your device.
