Upgrading to iphone 3G?

[marcw7174]

Hello,

I am in the UK and was wondering if i upgrade my contract for the new iphone 3g for £99, can i still use my existing sim card in my old phone and give the new one away?

Has anyone done this?

Many thanks
Marc

But yes, you can keep your number when you upgrade
