Hi iPad owners, I just bought an ipad and this is the first time i am using an apple product, I am obviously confused as a new owner. Please let me know your views on below mentioned caveats that i am coming across as a first time user. All answers truly appreciated. 1) Its an ipad 2 on "ios 5.1" , i have a pending update of ios 5.1.1---> Should i update it. Will i be able to jailbreak after updating my ipad2 to ios 5.1.1 and How ? 2) I heard something about ShSh blobs, what is with it that i have to do after the above is completed so i can avoid any mishap in future in restoring my ipad. Thanks alot.
