I have an e72, on at&t in a 3G location. Randomly, maybe like twice a day, it will just light up, but nothing happens, no incoming text, or call. I have the phone set to get email from my gmail throughout the day, every 15 minutes from 9a-5p, but the phone lights up during those listed time, no email. The phone also lights up outside of those times. Anyone have any ideas?
