Please Help... My iPhone is stuck in "connect to itunes" loop. I tried to restore, but I keep getting error messages (11 and 1600 I think) I think it can go into DFU mode, but I'm not sure... It's a black screen... But once it's in DFU, I don't know what to do with it.

I have Verizon iPhone 4, OS 5.1.1. I initially performed a tethered jailbreak with Redsnow, then I used Rocky Racoon to untether. Rocky Racoon had two updates since the initial untether which I updated.

Any help is greatly appreciated...
