iPhone 6 bought from carphone warehouse is locked to three
Please help, i bought an iPhone 6 from carphone warehouse and put a three sim card in which I've used for 2 years now. but i now want to move to EE so i can use it with the new apple watch 3 but no-one seems to be able to unlock my phone. three say speak to apple. apple say speak to three mean while I've cancelled my three account and I'm paying for an EE account that i can't use.
