its the same as the Curve 8900 not the others, its a micro USB where the others are mini USB.
Micro USB is the international standard for cell phones now so all new phones should and will be going over to this connection type....(Apple needs to join in too but highly doubt that will happen)
I have just received my AT&T 9700 without contract, it is a embeded US plug charger, interesting some website says it is universal with 3 different plugs, wonder is this only happens to AT&T?
