Motorola V710

I have heard that the 720 desktop charger will work with the 710 but the spare battery charge slot will NOT accommodate a 710 spare. I have also read posts that indicate an anticipated desktop charger for charging the 710. Anyone heard anything new about this or a way to charge batteries seperate from the phone? I want a second battery as a spare but cannot see the value if I cannot charge it seperate from the phone.

Thanks...
