In the Clock app, tap. To set an existing alarm, tap the time shown on the alarm. To create a new alarm, tap.; To adjust the alarm time, tap the hour or minute.

One measure of a true BlackBerry addict is if they sleep with their BlackBerry on their bedside table. I'm guilty of this myself, but it's mostly because I use the alarm program on my Berry. I find it quick and easy to use, much easier than fiddling with those darn buttons on your clock radio. You know what I'm talking about?
Anyways, in the first screenshot you'll see me hovering over the alarm icon. Click it to get into the program (Yes, I know BrickBreaker, Sokoban, CirclePopper and Ka-Glom are on the screen too... Texas Hold'em King 2 is just out of view as well :P... I'll review those later.)

Once in, it's super easy. Here's a breakdown of the options you can set:

Daily Alarm: Turn this ON or OFF to activate or de-activate the alarm.
Time: Set the time you want the alarm to go off.
Snooze: Want a snooze feature? You can turn this on to 1, 5 and 10 minute options. I've never used it, but I would imagine a lot of people do.
Active on Weekends: Turn this OFF if you do not want your alarm going off on Saturday or Sunday. YES if you want it to go off on the weekend.
Alert Type: Choose from Tone, Vibrate, and Vibrate+Tone. I leave mine on Tone for those early morning wake-ups!
Tune: Select the alarm 'sound' you want to use. Lots of choices here. I use the Alarm_Antelope. It's a bit annoying, but not annoying enough to make me want to throw my blackberry across the bedroom. PERFECT!
Volume: Choose from Low, Medium, High and Escalating. Find out what works best for you. I leave mine on High.
Number of Beeps: Select the number of 'rings' you want your alarm to belt out. Choose from 1, 2 or 3... I leave mine on 3.
Overall I'd have to say the alarm feature is one of the most handy available on the BlackBerry (besides the staples of phone, email and messaging of course!) I use the alarm feature every day and it never fails me... Well, sometimes I don't get out of bed right away but that's my own fault!

If you haven't used it before, try it. You might like it.

If you're using a BlackBerry 10 device like the BlackBerry Z10 or Q10, you may have noticed that the ringtone selection is a bit lacking to say the least. There aren't nearly as many built-in tones as previous BBOS devices - but that's ok. We have tracked down most of the classic OS5 and OS6 ringtones/alerts so you can grab them and easily transfer them to your new BlackBerry 10 device.

Astute? Assured? Lucid? ChiGong? They're all here and ready to be put to good use. Just grab the file here, drop it onto your computer and then transfer over the tones you want (all of them, duh!) to your BlackBerry 10 device. It couldn't be easier! Enjoy!
