750 owners.I just brought the 6.2 beta 10 over that can be found a couple post down.The only LED blink color we have been able to tap on the 750 is green.Good news though.Z has found some orange blink in that device so multi color led notifaction will be coming your way soon.Give beta 10 below and enjoy some voice alerts and green led blink.You will be seeing red and orange led blink sooner then you think
ENJOY
