Is SIM unlocking the same as jailbreaking?

) | asked June 26th, 2009 | 2 responses | “Great Question” (0

I have a UK iPhone but have moved to australia. Even though I am going to pay out my contract in the UK, O2 will not unlock the phone for use in Australia. I want to unlock it for Australian networks but still want to be able to upgrade the firmware and use the app store without having to continue hacking the phone. Any thoughts? Thanks.

Jailbreaking is replacing the iPhone’s OS with a tweaked version of the OS that enables the phone to do things like keep the background wallpaper on all the time or use apps that are unauthorized by Apple.

Unlocking is changing the carrier code of the the iPhone in such a way as to allow the phone to be used by a carrier of the phone owner’s choice.

My understanding is that you must jailbreak it first in order to unlock it. Then you can restore the original firmware so it’s no longer jailbroken, just unlocked. See redsn0w.
