[1.1.2] Just want to double check if correct way of upgrade
Hi just want to double check from what I read in the forum if i'm going to do the right way to upgrade and pwnage my phone.
I have a 1.1.2 OTB phone which I jailbreak& unclock with iclarified jailbreak and unlock tutorial using they're unlock tool.
Now here what i'm thinking of doing...
1. Use itool to restore my phone to 1.1.4 firmware ( I can't seem to find a program to revirginze my phone back to OTB 1.1.2)
2. Then use winpawn to unlock my 1.1.4 firmware
Any advice if this is correct is much appriciated :)
