At Motorola, we believe a customer shouldn’t have to dress up their phone for it to work properly. That’s why the DROID X comes with a dual antenna design. The kind that allows you to hold the phone any way you like to make crystal clear calls without a bulky phone jacket. For us it’s just one of those things that comes as a given when you’ve been making mobile phones for over 30 years.
