I've spoken to a technical support guy at Apple today and he confirmed that the T-Mobile contract free version is unlocked to all GSM networks right out of the box, I'll be picking one up when I visit Miami in several weeks for use in the UK as it's so much cheaper than buying the sim free model here!
I look forward to hearing about everyone's relief when they finally get theirs come launch day and it works as expected!
