Over the weekend I saw a pretty good deal at 3 for this phone, and as I'm just 10 days away from an upgrade I thought I would find out more.
Turns out it's £35pm on Pre-order, with no up-front cost. Sounds like a decent price, so agreed to go in and pre-order. Phoned O2 to let them know that I would be leaving and hey presto, they match the deal.
Phone arrives on 26th!
