The price of Blackberry's here isn't that expensive. The main ones you're looking at are gonna be around 2000-2500 (2000 for the Curve 8900 and 2500 for the BB Bold 9000, I just saw the prices today at Starlink, City Center)

I own a Blackberry Bold and I love the device (after using Nokia for years and giving the iPhone a try as well). To use their push email and BB Messenger (with which you can chat with any other BB device in the world for free, anytime!) and internet on the BB, you'll need a blackberry package from Q-Tel (something around 125 bucks per month).

Have a look at the phones at Starlink, I would recommend one :)
