I bought a multimedia dock from THIS GUY on eBay. I asked him if it would put the phone into 'dock' mode, but he wasn't sure. I figured if I had to modify it a little, it wouldn't be a huge deal. It came in today along with a new extended battery and battery door. I got the Motorola extended battery rather than take a chance on some of the other eBay offerings that I came across. Anyway, after putting the extended door on, the phone didn't fit into the cradle. So, off to the shop I go. I chucked the cradle in the vise of my mini-mill and started cutting a recess so that the phone would fit with the new battery. I also discovered that while there were indeed magnets inside of the cradle to put it into dock mode, they were in the wrong place! After cutting the recess (pics below) I took it apart and repositioned the magnets so that it would put it into dock mode. Works like a charm. All of the benefits of the Motorola dock along with the ability to charge an extra battery all for the cost of $25 + about an hour of my time.
