I'm now available for a free upgrade from Verizon Wireless and I was wondering which of these three phones I should get. I'm graduating high school soon and going to college so I'm not going to be using my email or internet excessively. I love each of these, but I'm a little weary on the Pre's sliding. Anyway, the three phones are: Palm Pre Plus, Palm Pixi Plus, and the Blackberry Tour. I currently own the Blackberry Curve. THANK YOU
