Verizon
The nice thing is they are not very expensive compared to some of the other Blackberries, and I don't think that they are different in quality. Verzion is running a special now for $150. It is really easy to use if you need all the features. I admit I don't use most of them...so make sure you will. There is a much cooler phone coming out from Verizon in the next week or so, so I would check that out too if you are looking for these type of features that the Pearl has. I can't remember the name of it right now... Happy phone shopping!
