What mobile phone company I should go..
Mmmm, for you a Blackberry may be lately the right thing for you. Other choices would be something similar to the enV, a Sidekick 3 or something similar. T-Mobile may be the best carrier for you.When did the sidekick 3 come out?..
I really have individual used the Treo. I guess it depends on what your looking to use it for specifically. I have never be a fan of the blackberry but thats my own view. I would say if you enjoy anything older that the 650 its time to upgrade. Try the 700w (windows). I love mine!
