I've been with Telus for 12 years and had the same number for 12 years. Before that I was with Rogers for 3 or 4 years and went to Telus due to a few bad experiences.
But I have only had my BB Curve for a few months. If I knew how dammed addicting the Curve would be I probably would not have got one.
Yep I'm glued to my Curve. Love it and all the features and of course still learning.
I've been with TMO and predecessors longer than I can remember. It started as Comcast, taken over by Omnipoint, then Voicestream. Sometimes when we travel, Omnipoint shows up on our phones. I think it has to do with who built the tower we're pulling off of.
