My MyTouch has several lights i would like to control for status feedback and notifications. What drves me nutz, though, is while my trackball would light up when i got a message or something, this phone would do nothing after the initial notification. My last two phones had a light that would keep flashing until i checked the device. The ones i had before would continue to sound off. What can i use to have something light up every so many seconds until i checked the phone?
