Yes, you can set the alerts to use one of many different combinations of the lights that are on the phone (there are different colored lights and you can set alerts to use different combinations of them). Shouldn't be too hard to see if you received a call/message or not. Some of the reviews are just plain wrong about some of the features so take them with a grain of salt. In particular, the review from Payton is almost 100% incorrect. Makes you wonder if some of these people have ever read the manual or even own the phone. lol
No doubt. I don't most of the Cingular customers read their manuals. I know I didn't before I started working there. But in actuality, a lot of the questions we answer on the phone come right from the manual.
