Version of Icecrown Realm?

Hi everyone,

Sorry for the noob question but what version is Icecrown Realm? Do I pick the Wrath of the Lich King(OLD) in the download list?

It's 3.3.5a, both Wotlk clients are 3.3.5a just the 'new' version has some races with the updated WoD models, but it's pretty buggy.

Thanks for the reply Zardonic

One last question please.
I have 3.3.5a how do I change it from Lordaeron to Icecrown?
