The phone itself was free as I was already an o2 customer and overdue for an upgrade. The tariff works out £5 more a month than I was paying before too (and with more minutes and a lot more free gadgets and wi-fi, etc) so well worth the move.
Downside is that my old phone is currently inactive and new phone won't be active for a few hours due to SIM transfer and charging the thing up. So I'm out of contact for the rest of the afternoon - if you need me email me or leave comments on LJ or Facebook.
I'm also currently setting up my old Ericsson so I can transfer the few pcitures on it that I don't want to lose.
