Plug your iPhone into your computer -> Open iTunes -> Press 'Restore'.

That's all there is to it.

Don't complicate matters by downloading your own IPSW file. Simply let iTunes do the work for you.

Do a "cat /etc/hosts" in Terminal. It should look like this:

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1	localhost
255.255.255.255	broadcasthost
::1             localhost 
fe80::1%lo0	localhost

If there's a line for gs.apple.com then you'll need to remove it. The easiest way is to use nano ("sudo nano /etc/hosts", remove the line, Ctrl-X to save and quit).
