I'm reading about downgrading iphone 4 to 4.3.3 using tinyumbrella with saved SHSH.
In 2 tutorials one says to edit the "Hosts" file by adding the extra IP address
( 74.208.105.171 gs.apple.com - for Saurik's server) at the bottom while the other tutorial says to delete the existing Apple IP addresses and add Saurik's.
So which is it? Just add one IP or delete existing and replace with one IP?
Thanks
