So, I've been trying out a Hero on Sprint for 3 days and I'm pretty pleased. The Yahoo Mail setup w/ retrievals at every 15 minutes isn't so reliable, but I found the gmail push to be awesome. Here's a question: I thought the trackball was supposed to glow when you receive mail, but it doesn't w/ the gmails i've gotten. Do I have something switched off possibly? I thought I had it all checked in settings. For that matter, I'm not sure when the led is supposed to flash or what. It just seems like you don't always hear a sound when email comes through like you do w/ text.
