First, does the iPhone 4s have only one firmware? I can't seem to find different firmwares for CDMA and non-CDMA phones.
Now the main question: I have a jailbroken iPhone 4s running 5.1.1. I never saved SHSH for this device. Now I wish to restore 5.1.1. If I understand correctly, I can use iFaith to extract SHSH blobs and APTickets from the device, upload those to Cydia, and then use something like Tiny Umbrella to restore the device.
Is that correct? Or does that only apply to limera1n-exploitable devices (i.e., iPhone 4 and earlier)?
Also, will sn0wbreeze allow me to create signed IPSWs for this purpose such that I don't have to use something like Tiny Umbrella to serve up blobs/tickets?
