Saw this post on Lifehacker:

I put the phone into recovery mode and I tried pwned DFU as well.

When I try to restore using the ispw I have been getting error 21 and error 1600. I used to get this before when I had difficulties downgrading my iPhone which I never got fixed.

Its a Verizon iPhone on 4.2.9. Tiny Umbrella isn't running. What should the host file look like for me to be able to ping Apple's servers?

**Edit**

Figured it out. Little Snitch was causing issues.

You are using the latest beta of iTunes to install, right?

If not, blame lifehacker for inept blogscraping.
