Anybody know what's involved with unlocking a TELUS i730?

The goal is to use either a Boost or a Nextel SIM while I'll be in the
US, without the need to purchase new hardware.

I've seen a few guides that mention unlocking Nextel and/or Boost
phones, but they seem to imply that the technique won't work for phones
locked to other carriers.

It's always darkest before dawn. So if you're going to
steal your neighbor's newspaper, that's the time to do it.
