guys i need help here.. i have a iphone 4 version 4.1.. i knew that 5.1 is the latest version but it's tethered Jailbreak....
so i think the best is upgrade to iphone 5.01 and do an untethered Jailbreak..
but how can i upgrade to only 5.01??
can i right click and upgrade specific ipsw, will it do the job??
