I have a Verizon BB Pearl that is in excellent condition. I've had it for about 4 months. I would like to change to a BB Verizon Curve. Let me know if you are interested.
Try getting a used Curve off the Marketplace forum here on Crackberry, or on eBay. Just be careful, and by all means pay using PayPal so you have some recourse if a problem comes up with the transaction (speaking from experience).
Personally, I like the keyboard better on the Pearl, which bugs me. But, I like everything else better on my Curve. If it's not my business, ok, but why do you want to switch? Good luck, BTW.
