I just got the thunderbolt and the original light is a blinking green one, I cant even tell from away if its blinking unless i check on it everytime to see if i got a text or message, I have the original messaging. I use to have handcent and that allowed me to have different led notification light colors, but handcent has been giving me a hard time so does anyone know if its possible to change this? or of a good app that will work for the thunderbolt?
