I miss the indicator light on my BlackBerry, and I'm wondering if there is a utility I can download to keep the screen illuminated longer when I receive a notification--say for 5 minutes or so. The behavior I'm looking for is the following: 1. iPhone is locked. 2. Email received pops up on notification center on lock screen. 3. Screen remains illuminated for 5 minutes, so I'll see the notification if I look at my phone anytime during those five minutes. I'm on an iPhone 3GS, so the flash notifier isn't an option for me.
