the link that i given to u is the latest ios for iphone 4....for ur info u will only able to update or restore to the latest ios(ios 4.3.5) UNLESS ur dad iphone 4 is jailbroken before n the shsh blobs is saved before...
so when u have finish download the ipsw open itunes and click ur device, hit shift and click update and then browse the ipsw file that u have download before...

Ahh thats explain why I am keep getting that error. I did intentionally try to restore to outdated which is actually my dad's current iOS because I am afraid the latest iOS won't be able to be jailbreak.
Is 4.3.5 is jailbreakable?

I think we need more info from Mr Docter on his dad's phone current firmware, what updated firmware he wanna restore to, and why the need to update....
The iPhone details are : Version = 4.2.1 , Modem Firmwire = 03.10.01.
The main reason why I want to restore it is because something wrong with Message. It won't responding once I pressed it; it hanged and quit by itself.
Thanks in advance, for both of you!
