I'm giving my mum my old iPhone 4 as i now have the 5, i just wanted to know as the 4 needs to be unlocked is it best if i swap my sim then unlock the old phone with O2 or unlock it first before swapping to the nano sim?
Or does it not matter what order i do it in as the unlocking is based on the phones IMEI number? I hope i've explained this well enough!

It doesn't matter. Use your current mobile number with the IMEI number and it will be unlocked automatically.
