Blackberry Curve  

I really want a Blackberry curve! and see i can actually get one with a contract but im not sure if i should because they job that i have is not promised so i dont want to open a contract and end up getting fired and not being able to pay my bill after a while for a two year contrct. So the Point is i want to know for the people with a Blackberry curve, how does it feel to have oe and how important is it to you how do you use it. and do you use it everyday! Do you use it for email and messageing?? Work?? or for talking?? or maybe all?? and if you have had a different phone before how is the blackberry better??
