Zurai said:No, actually it isn't. Both Lasting Frost and Wintertouched specify that you gain their advantages only when attacking with a power with the Cold keyword. While a Frost weapon can make your damage Cold typed, it doesn't grant the Cold keyword to your powers*.
* - not explicitly, anyway. It's a reasonable assumption, but there's not really any direct wording to back it up.
A frost weapon does explicitly give the cold keyword to your attacks:
p226, PHB: "When you use a magic item as part of a racial power or a class power, the keywords of the item’s power and the other power all apply."
