You can find the new Sleepers repository at http://repo.sleepers.net/cydia
Sleepers.net has also posted some information for developers...
We have seen many things since we have been hosting iPhone applications, one of the things that we felt the community needed was a automated process to handle the building of the actual packages for Cydia. Well it is DONE!!!
As a registerd developer you can simply upload your zip file with all of your screen shots, binary file, description and be walked through the automated package creation process. Once you submit your application one of our staff members will install it and make sure the package has been created successfully!
As we said in our previous post, you, as a developer gain access to many new tools that we have built for you, we feel the automated package creation tool is the biggest one, but we feel the second biggest one is giving you the ability to add your own ad code to the system to generate revenue.
We also do a few other checks to make sure the package is what you say it is and it does not install malicious code etc. If this is the case you will be banned from our network, so please do not attempt to submit packages that are malicious in nature!
To get started as a developer simply register with the system: http://repo.sleepers.net/register.php
