I just jailbroke my iPad2 with Absinthe 2.0. Seemed to work well. The Cydia icon shows up. When I try to install apps that I have already purchased I keep getting HTTP/1.1 500 Internal Server Errors as well as occ Hash Sum mismatch errors. Also some apps (PKGBackup for one) wont show any of the details when selecting them. I have tried hard reset. Any other suggestions.
