Apple Loyalty is an Uphill Battle
This is my brand-new Apple® Macbook Pro.

And this, is my brand-new Apple® iPhone 4. Ever notice how the Chroma key feature in Photo Booth always looks a little cheesy?

And this, is my 2003 “still-mostly-white plastic” Apple® Wireless Keyboard.

Despite being 7 years old, the keyboard pairs successfully with any device capable of pairing with Bluetooth keyboards. It even pairs with my brand-new Apple® Macbook Pro.
So, now that the iPhone supports Bluetooth keyboards, it only makes sense that I would try to pair them.

So far, so good. *tap* But wait, nothing’s happening. Maybe if I hit enter on the keyboard.

I see that screen for couple milliseconds, and then it’s gone, replaced by this:

I try it a few more times, and I try a few different things, but the same thing keeps happening. When I try Googling for a solution, I’m surprised that Apple admits the keyboard is incompatible, but won’t fix it. The fix, is apparently buying another keyboard for $70.
Or, buying any other Bluetooth keyboard on the planet. Generally, it seems pretty much any keyboard will work… except the one that Apple made in 2003.
