Apple's just launched its fourth-generation smart phone, the iPhone 4 ($200, two-year contract, AT&T), packing an ultra-high resolution display, a second camera for video chats, and some other new features that are bound to make some other smart phones jealous.

Meanwhile, Motorola unveiled the newest member of the Droid dynasty of smartphones, the Motorola Droid X. Available on July 15th for Verizon ($200 after a $100 mail-in rebate), the Droid X boasts a sharp 4.3-inch multitouch display, and an 8-megapixel camera that can beam videos to your HDTV wirelessly.

How do the two stack up?

We put these two hot phones against one another in a video face-off. I advocated for the iPhone 4 in my best Steve Jobs getup, while my colleague, Paul Eng went to bat for the new Droid.
