Thank god i'm not the only one!
Rebooting doesn't help here, so i'll give it a couple of days before i'm taking a flight to Saurik and ask him some "questions" before i force him to fix it.
What do i suppose to do now then?! Do some important stuff that really needs to be done? No. I want a functional Cydia now!
Anybody else out there with the same problem? Come and join our growing club!
