Hey everyone, recently purchased a MBP in the USA and i like in the UK. it's been great, but i was wondering, if i took the extension cable from the magsafe (not the magsafe adaptor it's self, but the extension cable that plugs into it) to my local apple store, do you think they'll be able to swap it out for a UK one as my MBP came with a 3 prong USA one?
