This includes an O2 pay as you go simcard with £10 top-up.
I spotted this when I was looking for a small and compact second phone. I saw it going for an average of £200 elsewhere.
I'm not sure if O2 phones still come unlocked like they used to but I got my Blackberry in May this year and it was already unlocked. Also, I know that contract customers can get their phones unlocked free of charge by calling up customer service. Pay as you go customers may have to pay a small charge.
