Funny legal compliance
In the UK they don't comply with the most basic rules.
Get an iPhone through a mobile company and try and send it back within warranty period.
They won't take it because Apple insist that you go direct through them. They then try to claim that you have to promise to pay them something stupid like £120 if there's no fault with the phone - and they'll take that off your card at their discretion. Then they ship you replacements and collect yours.
That's totally illegal. Your contract is with your vendor - in this case the mobile phone company. And it's them that are legally responsible for returns.
