What do you get for that £20 Roy? I take it you would still qualify for upgrades if you choose to upgrade to the new one when it comes out? Did u bother with o2 insurance?
£20 a month Simplicity gets you 700 mins, 1200 texts and unlimited web.
I can't fucking wait to downgrade off this £35 a month one - I'll be doing the same as you, Roy.
Also, I don't think they offer any upgrade options on the iPhone anymore. Once your contract expires you simply get a new one. The bonus is that you can sell your old handset for a pretty penny if you've looked after it.
