I have a HD2 on order and am looking forward to it next week !
But, the cradle remains unclear. I have the HTC CR G300 with a HD and I doubt very very much that this will fit the HD2 as the photos I have seen show the USB connector as slightly offset to the right.
In my humble view the HTC CR G300 will not fit.
Now, the car kit - this looks great and I'm tempted. But, until now I have not been able to discover if this has a data channel or only power. I suspect due to its intended function in the car that there is no data channel. So, use on the desk with PC is out.
I remain open on the car kit ...
