Warranty warning to anyone not buying a UK version phone?
put this into Google and do your own research
(Lack of International Warranty/Customer Service)

Would this phone work outside UK?

Yes but before you take it outside the UK, simply make a call to any UK number (while you are still in UK) for at-least 6 minutes. This will remove the region lock and after this process, phone will then work with any network in the world.
