Yes I am running it right now with a Telus P4000, if you know howto reprogram your phone if it all goes to hell (and it will
)then go ahead but definately skip the customizations at the start, caused me a lot of greif when I let them run the second time.
I can NOT confirm if Rev A is working for Telus, but I was able to connect through evdo and make calls after reprogramming.
