Any word if they're still signing after the 4.3.1 release today? Hopefully so.

Here's what I did
1. iREB-r4 put the ATV2 into pwned DFU mode
2. Ran TinyUmbrella tss server (yes shsh blobs for 4.2.1 8C154 were saved)
3. Started iTunes 10.4, right-clicked and chose 4.2.1_8C154_SP_Restore.ipsw file. iTunes went through some steps such as restoring and verifying without problems, then as it was verifying a second time I got a error 1600.
Thanks guys.
