I gonna tell you how I installed everithing on my last reflash (one day ago)
First; delete all existing repos on your app manager
second: go to gronmayer and download every single repo for your os (be carefull to download the proper one) (if your OS is 2008 you will see that the first two or three repos does'nt work; don't care about, install all the others including the temp fix ones!)
after that, you will be able to install almost all the apps available for your OS. If any app is not listed, then go to Maemo and install the individual app from there.
