I think an agreement among some of the mfgs is in the works but, in my experience, the mini-USB that charged my BB did NOT charge a Motorola (RAZR, I think) phone with the same-looking mini-USB port - very annoying! I don't know if the micro-USB will charge Motorola's with that port or not. However, the micro-USB for my 8900 DOES charge my wife's LG env3! I hope they're "coming around" with agreements all this nonsense.
