I've just upgraded my iPhone 4 to iOS 5.0.1 and also jailbroken it. I've waited with the upgrade until the jailbreak because there are some tweaks I don't want to miss. Now that I have iOS5 jailbroken, I want to re-add those tweaks, but I don't find them in Cydia.
Looking at the sources in Cydia, I see that
Cydia/Telesphoreo are listed and they do contain lots of items, but
Big Boss and
Dev Team and
cydia.zodttd.com are also listed, but when I select each then there's nothing in there.
So it would appear that some of the repo's are not properly set up. To test this, I removed
Big Boss and hit the "Add" button to add it again, but got an error message "Did not find repository".
