Which phone should I get?

I have been wanting to get a new phone. I dont like sprint for two reasons. 1. I am getting charged for things that I dont use. 2. I have the touchscreen instinct and I hate it. It is always freezing up when I am texting or playing a game. Half the time i have to take my battery out to restart it. I hate it. Anyways, I cant decide between the blackberry curve or the palm centro. I get on myspace and facebook alot. I am alway google something, and I text all the time. I have heard good things about both. A girl I know just got a curve and she said she loves it, but she cant send pictures with hers, I also heard good and bad things about the centro, a girl I work with says she absolutly loves the phone but it keeps taking forever for her text messages to go through and the phone keeps shutting off. I dont know which one I want. I like them both. I read that the curve you have to pay for usage and stuff, and the centro you dont. Which one is better?
