What kind of phone? Do you already have a USB to mini-usb cable? Belkin (and many others) make 12v to USB adapters, some of which even give you secondary features like flashlight or whatever (Sosche has one like this). This is the kind of setup I was using for my iPhone before switching to my current head unit.
As far as mounting one in the center console, there are some pass-through kits for USB (possibly even mini) that you may be able to make a 'mount' out of that I've ordered from Allied Electronics in Fort Worth. You'd have to check the current catalog for all of the offerings.
If you wanted to do something cheap, get a 12v to USB from MonoPrice and hide that in the dash/console, then take a standard USB2 cable and adapt it back to USBA (or use a USB extension type cable) giving you a receptacle that you could actually hard-mount somewhere. That might be nice looking when you are unplugged. There are a lot of possibilities. MonoPrice is a good cheap place for looking for ways to create your own solution.
Someone may offer a complete MiniUSB off the shelf, but I've not run across one. Having standard USB may give you more options down the road anyway.
