Status Notifier. I knew that I would miss the status bar icon for new mail, but I had forgotten how stupid the silent mode toggle is. The icon for it is so natural that I forgotten it was a jailbreak-only feature! That apple still haven’t added an icon for this after three years is amazing to me.

Yes you can look at (or feel) the side of the phone to check – but the problem is I regularly forget that I have silent mode on and just stick it in my pocket without a second thought. I have missed a number of phone calls and countless SMS due to accidental silent mode. It’s ridiculous.
