What is one feature from another phone that you miss in the iPhone?

Before my beloved iPhone 4 I used to have a hand-me-down Blackberry Curve 8310. I hated the damn thing, but the one thing I miss from it is its LED notification light. Not the ever-blinking service light, I turned that off in an instant. But if I had a text, email, anything I hadn't read yet it would blink non-intrusively, and it would catch my eye without any effort from me. It was completely passive.

On the iPhone, the new Notification Center is great, but that requires an action from me. There are not even status bar icons, and even on the lock screen I have to wake my phone to see if there's anything I missed. With the Blackberry, all I had to do was look down and see if the light was blinking. I could do it while reloading my Scout's Force-A-Nature, without lifting a finger from my mouse or keyboard and risking being shot.
