Did you know that you can set alarm on your phone even when it is turned off? This is quite useful feature for people who usually turn their phones off while sleeping. For you who always turn your phones on, this feature might not be interesting. Actually it is not only a feature of S60 phones; some other non-S60 phones from Nokia has this feature too.
How do we setup this feature? There is nothing special. Simply set alarm in the Clock application as usual. Then switch off your phone and go to bed. Next morning, when the alarm is ringing, you can stop it and the phone will be switched on automatically. Alternatively, you can also select snooze if you still want to sleep.
