Will the Gevey Sim still work in UK??

[nk786]

So I'm planning on going to the UK and was wondering if my Gevey Sim will still unlock my iPhone 4. I'm currently using the phone with T-Mobile USA but I'm going to have to purchase a pay-as-you-go sim on a different provider (o2, orange, etc.) when I'm in the UK. Does anyone have any experience with this? Thanks in advance!

Unlock is an unlock. You can't unlock it to just work on a particular carrier. I don't use Geven but does Gevey Ultra Sim say that it only unlock it to use it with T-Mobile? I doubt it.
