Heading to England for a week

[theDreamer]

Heading to England for a week for some vacation and looking at my options of phone use and that sort of thing. I currently have a HTC Touch Pro on AT&T (AT&T Fuze), running eliteR3 - 20090115.
Do not think I will need to be calling home at all, but what about calling people who are in England while I am over there? I know I will need to unlock my phone, but can I buy a cheap SIM card here that will work over there?

Thanks for any help.

Buy a prepaid SIM at any shop that specializes in mobiles or at the airport.

Will I need to unlock my phone or anything or will I be fine with just using any SIM I pick up over in England?

Thanks.

You'll need to unlock it.
