On my second Blackberry with VF and soon to be a third one when my contract expires in April.
My daughter (20) today got a new VF phone; she was on XT pre-paid until yesterday. She and her friends text mainly and the primary reason for the switch was not the outages (in Christchurch) so much as the persistent delays in receiving texts (I posted about this in December). She tells me that a lot of her friends are, or have made the switch to VF.
Actually yeah, I have a XT prepaid sim in a sierra wireless aircard 880U that I got off trademe for a few dollars that I have fired up a few times when out with the lappy. Might be coming up 6 months, better check that out since if it expires it will be annoying.
