Big selling feature for the Moment over the iPhone is swapable batteries. I'd like to keep the phone with me at all times, and just swap in batteries. But I can not find an EXTERNAL battery charger. Google search only turned up a "universal" charger where the contacts are manipulated to match up with the battery. Not a good option. Anyone have a source for an external battery charger which I can use to charge spare batteries without using the phone?
