MyAlarm allows you to set songs to play when you set an alarm in iOS

  MyAlarm is a new tweak specially designed for application Clock of our iDevices because by installing it you will be able to use songs for the alarms set in the application. More precisely, the tweak has in the settings menu in the Settings application a iOS, and there you can choose the songs that you want the alarms set by you to play, the songs being taken from the music library of your terminal. This option is not natively available in iOS 5.1.1, but in iOS 6 Apple implemented it, so the tweak will be useless from the fall.

MyAlarm is a tweak that lets you play music from your music library instead of the system tones that apple provides for the built in Alarms. All you have to do is go to the MyAlarm tab in the settings app, press "Choose Song" and choose the song you want for the alarm, and press "Set Song As Alarm". Alarms will now play that song when they go off. The songs also act as normal a normal alarm. When you slide it away the song turns off. Snooze is also perfectly functional with this tweak as well.

  Until then, you can find the MyAlarm tweak in Cydia's BigBoss repo, but it only works if you have at least iOS 5.x installed.
