OK, so I'm reasonably set on a Nexus 5, on O2 (who I'm with at the mo). The question is, who do I get it from? Someone in an O2 shop told me about "Refresh" which seems interesting - a certain amount of your monthly bill goes towards paying for the phone, and some to the line rental etc. Once you have paid off the phone part (You can pay extra amounts whenever you want), you can change your phone, and if you want to go to a different carrier, they waive the rest of your airtime bills.
One thing is, O2 want
