Has anyone had any luck getting any of the cellular pc cards that Cingular sell to work in a PB running 10.4.3? I do not wish to have to pay $80/month to use Verizon, when I can get a $60/month unlimited plan from Cingular (plus a 17% discount for working for one of the companies they give a corporate discount to), who is also my wireless carrier. Unfortunately, the people at the Cingular store look at me like I have 3 heads when I ask if they have anything that supports OS X :alien:

I've seen OS X drivers at smithmicro.com that are for the Sierra Wireless cards that Cingular sells. Has anyone been successful using these?
