out-of-left field suggestions.. I saw some induction type(which may still need some attachment to the phone) charger. However, a while ago, I also saw an inductive charger, for the Wii remote, where it does not appear to need any attachment -- for that package the manufacturer also provides a set of battery, may be they customized it with some additional h/w in that battery.

the next best thing would be the ebay BL-5J battery/clone charger
