When I was growing up, if the phone rang in the middle of the night you knew it was some kind of emergency. At least that’s the way it was in my house. And so when I got my first cell phone, I decided that it had to remain on all night. You know, just in case there was an emergency and someone had to call me. Yet in nearly a dozen years of cell phone ownership the number of times I’ve been summoned for a post-bed emergency is exactly zero. (And no, booty calls do not count as an emergency.) On my BlackBerry I can utilize a few easy methods to keep away those unwanted callers. Bedside Mode In the Clock app you can click Menu and go to Options to find Bedside Mode. It’s a nifty little option that lets you choose different features to disable while sleeping. If you use your BlackBerry as an alarm but find that the blinking LED sometimes wakes you, you can check the Disable LED option. If you charge your BlackBerry while sleeping, you can choose to dim the screen. That way your clock is still displayed but the brightness won’t distract you as much. If you want to go all the way, you can completely disable your radio in this mode. You can do that by other means, too, but if you want to combine it with dimming the screen this works. Finally, you can change your sound profile — which again is an option you can do standalone. Radio off If you just want to turn off your radio at night and prevent anyone from waking you from your slumber, you can simply go into Manage Connections and turn off your connection to your mobile network. Simple solution to a simple issue. Custom profile If you want to create a custom profile that turns off all sounds, you can do that as well. But if you want a few people to be able to reach you — mom, dad, spouse, siblings, etc. — you can create sounds for specific contacts and leave them as exceptions. If you don’t need the screen dimmed, which is best done in Bedside Mode, this might be the best bet.
