iPhone App - Blinking Notification Light On Screen

Hi,

I have been wanting to switch from an Android to an iPhone, however, there is an app with the Android called LED Blinker Notifications seen here, that has kept me from it (there are other similar apps, but that's the one I use). It is a small blinking light on the front of the screen as a notification. You can set the light to different colors, sizes, etc. for any app on your phone. For example, I have yellow set to missed calls, red to text message, blue for face book, etc.

The benefit is that I don't have to pick up my phone all the time to look for messages for I will catch it in the corner of my eye. I realize you can make the light on the back of the iPhone flash as a notification; however, its pretty obnoxious and you can't change it per app.

This feature on the Android is a deal breaker in regards to switching back the iPhone. I'm really hoping that the feature has come available and there is an app for it.

Does anybody know if this?

Thanks,

Aaron
