Open up the hosts file in NotePad (Win) or TextEdit (Mac) and add the line: Code: 220.127.116.11 gs.apple.com ..at the end. Save it. Then put your iPhone 3GS or iPod touch 3G into DFU mode and shift+restore to your 3.1.2 firmware. If you get any errors ignore them and repeat the shift+click restore process. The line you added in the hosts file will spoof the activation to Cydia's server for activation. I'm presuming Rock uses the same address to save your ECID SHSH signatures. Note that you may need to use an earlier version of iTunes. If you're having problems then download and install iTunes 9 from filehippo.com. For more details on ECID signing see Saurik's article here" _________________________________________________________________ I was wandering if I can use this method to downgrabe my iPod touch 2nd gen MB model?
