today at work, i got the dreaded spinning wheel of death. i tried restoring to 3.1.2, but iTunes wouldn't let me. i looked around and found some guides, and it said to have the 3.1.2 ECID SHSH on Saurik's server (already done), and add an address to the hosts file on my mac. i did that, and it still wont let me restore. can someone point me to the right direction?
