Yea I haven't been able to download anything from cydia with the new jailbreak. But you gotta remember most people with iphone 4s and ipad 3 weren't able to jailbreak yet so I'm sure cydia is slammed!
Which iDevice are you using?
I was planning to jailbreak my iPad 2 with the new Absinthe, but if people are having problems, such as not even being able to download from Cydia, I may reconsider.
