I'll believe it when I can actually do it. Right now all the DevTeam has given us is vaporware--videos claiming how easy it is to perform the JB and vague claims that they may eventually release a program or a protocol to the public.
Nothing but hype insofar as I can see.
Granted. But considering the dev team came through with a hack for every single firmware from 1.0 to 1.1.4, I'd say they've earned the right to be taken at their word.
