Strange, very strange. The icon *should* be blue, as it mean paired device connected. You mean that the other one works without bluetooth icon turning blue?

I can't say for all the "inventions" meant to work with ipads or whatsnot. I have never seen a keyboard, mouse, or keyboard+mouse pair that works over bluetooth and isn't working with N900 from start/can't be made to work, using extkbd and extmou. But maybe there using some twisted BT standard for apple nonsense, just like with audio-video cables and switched ground (just analogy, not technically at the same level)...
