Other than that I don't think there is a RIM branded charging pod available for 8500's like other Blackberry devices. The 8500 series has no contacts for charging the phone (other than through the micro usb port) So I don't think they can make one, unless they somehow make a new battery door that makes contact with the battery. Why RIM would do this? I have no idea.
So to the OP I think your SOL unless Powermat (or whatever the other company is) eventually makes one. Which would change the battery door.
for the new curve just by one of those inexpensive leather stands and just plug into the usb port....
I don't use a pod anymore on my 8330 cause of my innocase, but it did save wear and tear on the usb port when I used it. Wish they made an adjustable pod, like apple does with all their adapters.....
Any idea if a magnetic type charger would work like some of the newer electronic devices have? Maybe this is a possile future enhancement to the chargers.... Otherwise that eBay one looks decent enough.
