HTTP/1.1 500 Internal Server Error after Jailbreaking with Absinthe?
A bunch of our users have been reporting receiving the error HTTP/1.1 500 Internal Server Error after jailbreaking with the recently released Absinthe 2.0 tool. This error is normal and has nothing to do with the jailbreak process. The problem is that with so many people jailbreaking all at once, and all the newly jailbroken devices, Saurik's Cydia servers are getting flooded with traffic.
Since the servers can't handle the traffic, you receive this error. Just keep trying and over time the traffic will smooth out and Cydia will continue functioning like normal. Until then, you just have to live with it.
