I have been trying to refresh service with no luck. I can login and get to my personal repo but can not install the repo in iPhone .

Is this still available for users?

Unfortunately, this is one of those weird yes and no moments...

Installer is dead. It is no longer maintained by Ripdev, the original developers of the application. Nor is it being maintained by anyone else as far as I'm aware of.

As result of that, Installer repositories are mostly dead, or semi dead (much like this one), or completely unmanaged.

As we do not keep local copies of packages, there is no guarentee that packages will continue to work. Additionally, the repo.sc domain is in some strange limbo right now, so the only way to access your repository is via: http://www.touchtoolset.com/repo/<username> IE: Touch Toolset - View Profile: TTS

If packages are not working in Installer, chances are, the hosting for original package is no longer active / available.

It is recommended that you update to use Cydia instead, which offers better package management, and better dependency tracking. Using Cydia will also not need a middleware such as this site, as it manages the repositories much more effectively than Installer does.

yes im now using cydia but it cant find my repo and i have been tearing my hair out trying to get this to work

I am also facing the same problem, can somebody give me a solution as to how do I install calldata on my iPhone 3GS os 4.02
