Jailbreaking, Pwnage, Error 21 in iTunes

[ace of nothing]

Had a small problem jailbreaking before and this forum solved it in 5 minutes. Let's see how long it takes this time.

Using Pwnage I got all the way to the restore and after about 30 seconds I get "Error 21" in iTunes saying I can't restore.

Any ideas on how to fix this? I am using a new MacBook Pro which after a quick google of the problem might be the culprit,

Try using a USB Hub.

Use a powered USB hub

Use a PC

Use a Mac that doesn't have OSX 10.5.6

Any of those options should work.
