could someone please direct me to the most reliable / trustable website for jailbreaking ipads?
Evasi0n is the only tool to use. Do not and I stress DO NOT use anything else other than that. The process takes 5 minutes and is the only way to jailbreak ios devices. You cannot jailbreak anything above ios 6.1.2 and the next jailbreak planned will be for ios 7 which is due to be launched next month sometime.....the jailbreak may be release a week after or a year after......nobody knows!
the jailbreak for iOS 7 and even iOS 6.1.3 are availables
