Unlocked HTC Raider ICS update, canadian version of HTC Vivid

[plparent]

I'm considering on converting myself to the Android world, I was previously with Blackberry.

I'm looking for an unlocked phone since my carrier doesn't offer much device choices.
I found an HTC Raider, equivilent of the US HTC Vivid, and was wondering if I will be able to update the phone to the latest Andoid OS, since HTC's updates are given by the carriers.

So let me make my questions clear:
1- Are unlocked phones updatable?
2- Will I be able to update my HTC Raider, even though its unlocked?

Thanks
