There have been many requests on the XDA forums for the bottom key LEDs on the HTC EVO 4G to flash for alerts such as SMS notification.
XDA forum member bludragon742 took on the project at the beginning of August and after listening to XDA members thoughts and ideas on how best to make the app work, has now released the first version of his WiMAX Notifier app!
The notifier app gives the options of a number of colours for the LED, and currently works only for SMS notifications. The dev mentions that future versions will handle MMS, Voicemail, missed calls and more. Currently, the app requires root privileges but bludragon742 has stated that in future, WiMAX Notifier will work on non-rooted devices.
