Belkin is already on my bad list. I bought a USB hub / iPod dock from them a while ago on Woot. When I opened it up, there were a bunch of inserts for compatibility with different versions of iPods and a notice that I could request new inserts in the future.
So, then I got an iPhone 3G. It fits on the dock and works, but there is no insert for stability, so I wrote to Belkin to request an insert... Their response is that this device does not work with the iPhone. I know for a fact that it does work, and given the (mostly) standardized iPod connector, there's no reason this shouldn't work.
I think that Belkin stopped making this model and no longer wants to support it, so instead of saying so, they simply lied and told me that it wouldn't work with my iPhone.
