It is an unbranded phone with an Orange sim, so if you're using Orange care you'll have to cancel it and get a replacement. I used http://www.cusc.co.uk/
and they charged £60, don't know if there's anyone better out there. If you've used Orange Care and had my experiences of it (I had the Original SPV back in 2002; I think it broke 5 times) you'll have found it to be quite good, so this is a bit of a downside.
I got it from Phones 4U. They tried to tell me to change to an animal contract, but I persisted and told them Orange told me I didn't have to (complete lie) and it magically became possible.
Carphone Warehouse also stock it, but said they couldn't do the upgrade with my pre animals contract (don't know if that was true or not).
One word of warning; Phones4U can only access your Orange account once within a day, so if you ask them about it and they log into Orange to see how much it'll cost you; any humming and hawing means you've got to go back the next day to actually do it!
