I am A sprint customer and Ive had a Treo 755p for about 6 months or so (started with a burgundy, then got a blue one). I have loved my treo, all its features, especially Threaded SMS, fast web, and other palm features like the silence up top etc. While i like most features of my treo, Ive gotten tired of its lack of sleekness (Its fat), and while i like the size in my huge hands, the keyboard is a bit nimble for me. So im just ready for a new smartphone and a sprint curve has been on my radar for a while.

So i comes down to Is the curve a decent enough upgrade from my aging Treo, or should i await a new blackberry like the upcoming bold, or a who-knows-when new Treo? Id appreciate any suggestions.

Note: on a sprint plan whats the cheapest way to use a blackberry still using text, internet, email etc?
