Hi,
I upgraded my firmware to 5.1.1 and used Absinthe 2.0.4 to jailbreak and everything worked fine no problems. Unfortunately Cydia will not open though. It flashes then crashes (goes back to the home screen). I have tried wiping clean and then using Cydia, and even that doesn't work. Any suggestions??? Thanks in advance.
If you have an iphone 4 you might try using the current bersion of redsnow to jb as you can use the older limerain exploit to jailbreak. Maybe that will solve the problem.
