It is the dead end. No exploit has been found. All of hackers are joking around to fool you.
The new baseband made it the stainless steel wall.
That is it for it.
TOo, bad.

I think I have followed all of those steps and successfully downloaded and installed cracked apps directly into my iPod from Installous, but when I tried to to run the apps, the screen app pop up for few seconds and went away back to the home screen. That happens with all the cracked apps I installed. So what have I done wrong?
