Does it lagg more since its jailbroken?
Mine doesn't work at all.
Let me explain.
Used redsn0w 0.9.6b6 Window-version and did the jailbreaking. Then installed Installous 4 and shut down the iPad.
Now what?
Device no longer starts.
Now downloading pre-jailbroken IPSW for iPad to do complete restore.
Life is funny, eh?
