I just jailbroke my iPhone 4 yesterday. I had 4.3 and upgraded to 5.0.1 and jailbroke. I have jailbroke many times in the past and haven't come across these problems. Does this all have to do with the Cydia servers getting hammered? Below are some sequential screenshots of what happens once I open Cydia and then when I go to installable purchases. Also, even though I click "remember me" on my sign in to the manage my account page, I have to sign in every time.
