I have two Touch Diamonds. The formfactor is proprietary...it is not a standard shape port. This is very annoying.

I tried ordering a charger from ebay like I do for every phone I've ever had and they send me a mini-b style usb charger instead of one that fits my Diamond phone. I email them telling them that they said the charger was compatible but in fact it isn't so they quoted some poorly written sprint page about the phone and charger compatibility.

I took a picture of the port and sent it to them. That shut them up pretty quickly.

The stupid HTC style port doesn't hold the usb connector as tightly as the b-shaped usb does.

No they aren't compatible. Check out some pictures of the Touch Diamond via a google image search and you'll see.
