Help New phone, old sim?

Hey, I have a xperia x8 with an o2 simplicity sim card.

When I get the Samsung Galaxy Ace, could I just put my sim into that phone?

I don't see why not. I've been moving sims between phones without any problems for the last couple of years. As a matter of fact, the sim I'm using now in a Nexus 1 and Samsung Captivate was originally from an old Windows Mobile 6.1 phone.
