I have an lg env3 and it has a broken screen, so I want to get a new one because I don't like it anymore, I want to get a blackberry curve 3G so I want to know exactly how much it will cost.
If you're still in a contract with Verizon, you will pay the full retail price if you switch to a new phone from Verizon. That price for a Blackberry Curve is $365.
To save some money, you could try to buy a Verizon Blackberry Curve on eBay instead, new or used. If you do that, once you have the phone, you can call Verizon and they'll switch you over to it. Just make sure the phone you get is a Verizon phone and has a "clean ESN" (the ad should say that, or ask the seller).
