Simple question, hope to receive some simple answers. I'm getting a Droid X and the main thing I'm after is being able to use the internet while on the road. Verizon has a Smartphone Data Package which I chose Unlimited email and web. I thought that was all I needed. After scrolling down on their site I see an optional Wireless Internet Access. Do I need to purchase the Wireless Internet Access along with their Smartphone Data Package to be able to do what I want?
