One more little quirk/fault, but easily corrected with a restart. I leave my mail app open for the wonderful constant updates and notifications. I can't tell you how much I love this feature. It's like getting the great Blackberry mail without giving up S60 or getting locked into Blackberry's proprietary little world.
But after two days with the phone constantly on, plugged in at night for charging, unplugged in the morning to be slipped into it's sleeve and my pocket for the day, my E71-1 quit responding to the dedicated Messaging key. All other keys functioned normally, and I could access mail via the Menu > Communications > Messaging. I also noticed that I would receive the "new message" alert tone, I would see the little screen icon in the upper right for new mail, but I wouldn't get the home screen notifications for email or SMS/MMS. The mail was there and I was alerted, but no on-screen clickable notification. A simple restart cured it and my E71 was back to normal in less than a minute. But there it is. The entire Messaging program lost connectivity with the home screen and dedicated key.
