Best Sprint Phone Right Now?

[rainingsun]

I'm 12 years old living in LA, California. I'm going to get a Sprint phone in the summer this year.
I "need" a phone that:
- is touch screen
- has a good appearance/insides
- easy to use
- Twitter / Facebook app

I "want" a phone that:
- has a physical keyboard

It can be a smartphone, by the way.

I was thinking about the Palm Pre, but I think the keyboard's too small, but I'll think about it again.
But recently, I have been thinking about the HTC Touch Pro2. But it's so expensive.
Do you think it's normal for a 12 year old girl to get a Pre or HTC (smartphones)?

Also, does the HTC Touch Pro2 / Palm Pre have a Twitter application?

So what's the best Sprint phone that's out right now with the "needs" and preferably the "wants".

Thanks.
