I'm not new to the unlocking scene (I had followed it for a good amount of time), I am however, new to actually unlocking my iPhone. I will be traveling to the UK for Christmas/New Year's and have a Jailbroken 1.1.1 iPhone. What will I need in order to just land, pop in a prepaid Vodafone or o2 sim and start talking? I've gotten a bit confused since the 1.1.1 updated came along. Thanks and feel free to delete this thread after I get my answer.

Is it as simple as installing anySim from Installer.app? Thanks.
