They won't until there's a reason to sell them. If they lost Vodafone they'd truly be knackered, they at least have that outlet now - and ironically, that is probably good for Vodafone themselves, because they can offer a point of difference to the other carriers, i.e. want a BlackBerry? You need to talk to us....
For now, BlackBerry at least have a chance, and if via Vodafone sales improve, then the other carriers will pay attention.
