My cell phone company is Verizon wireless, I have a plan there and number/etc. I am about to purchase the Sony Ericsson Xperia X10 phone from Ebay, and I'm wondering if I bring this phone to my Verizon store, will they be able to transfer my account to that phone?

The Xperia phone isn't sold by verizon, but they do sell other phones by the Sony Ericsson brand. I've heard of people bringing their phones to Verizon and getting their account put on those phones even though Verizon doesn't sell those phones. Is this possible? I just don't want to waist my money.

Also, I have tried to get help from the Verizon Customer Service online and on the phone. Also I've tried the customer support line with Sony Ericsson, I'm having no luck at the moment.
