Buy iPhone 4 on AT&T in US, use in UK

[towellys_dealer]

I've scoured the forum and not come up with an answer, so apologies if it has been brought up before.

I have an iPhone 4 on AT&T, bought in the US. I would like to use it in the UK, but am unsure if it's possible to unlock it for not only a different network, but different country. Is this possible?

When you unlock the iPhone, or any phone for that matter it will work with any network anywhere in the world.

You need to check which baseband (modem firmware) version your phone is on to see if it can be unlocked. Currently only iPhone 4's on baseband 1.59.00 can be unlocked. To check your baseband go to settings > general > about > modem firmware...

??? Mine shows 03.10.01 and is unlocked, was bought in France though.

Yours will be factory unlocked then. Says so in your signature...

Right.
