The INCS Canadian NAM (Canada) ICS upgrade, is now available from the htcdev website. Forget about a Bell release, but if you want the stock ICS upgrade without s-offing and routing your phone, you can get-it from »htcdev.com/devcenter/downloads
The only thing you'll be lacking, is the Bell bloatware. But, if you want part or all of that bloatware, it is available on the Google play store.
BTW, this is a stock non routed and no s-off upgrade, so, if your device is still under warranty, you shouldn't lose-it.
