I upgraded my ipad2 from iOS 5.0 to iOS 5.1.1, use absinthe 2.0.4 to jailbreak it. However, I was new to jail breaking so follow the 'readme' file attached: backup before jailbreak, jailbreaking, restore after jailbreak. Later on only I find out restore means unjailbreak. I reset it n try to jailbreak again but an error msg said device already jail broken. I really wish to jailbreak it, any1 knows any methods tat I can jailbreak it again? Really thanks a lot!!
