I have an iPad2 and have read ALL the steps on how to upgrade 5.01 to 5.11. I have blocked the IP address through hosts files and also used tiny umbrella. I get an error that says " Ipad2 isn't eligible for the requested build", and also i get " an unexpected error 11 occurred".

In tiny umbrella, under the advance tab- the set host to Cydia on exit is GHOSTED out.

So, how can i update to 5.11. I need this update because ********** does not work, since it needs i higher firmware.
