Guys, guys, guys... Take a deep breath and relax.
First do a fresh restore from itunes latest version located here:
Windows and for
Mac And
Windows 64 bit
Then download the correct IPSW for your iPhone here:
iPhone 4 GSM -
iPhone 4 CDMA
Then install iTunes, restart if required. Start iTunes, for mac users, press "option + restore" select the downloaded IPSW. For Window users, press "shift + restore" select the downloaded IPSW.
If you get errors, then locate your host file, remove the 2 bottom lines that points to iTunes/Apple servers, and do the same thing again.
Then if all went fine, restore your iPhones from a backup in iTunes. When done, you should all be back on stock IOS 5.0.1 now. Good, thats what we want.
Download Redsnow latest here:
Window Users for
Mac Users
Unpack the downloaded file to a folder of your choice. Then start Redsnow, hook up your iPhone guys. Then just hit "Jailbreak" and wait, this can take up to 5 mins to complete, but when done, you should all be "jailbroken" untethered now. Assuming you are up and running, start Cydia, and download the tools you need, like SBSettings, Winterboard and other tools. Do them one by one, or you will might end up again with same problem.
Have a great New Year all.
