Alarm tone: I tried different ones, for example the typical "Morning mood" by Edvard Grieg and Sigur Rós' "Hoppipolla". Currently my alarm tone is "Pellonpekko" my Korpiklaani.
Depends I have different ringtones for different people. For Example my Sweethearts ringtone is "Need you now" Lady Antabellum, while for my brother the ringtone is "I won Coffee" since him and I only go out fo coffee these days and my best friend's (Elvi )ringtone is "Happy" from Pharrell Williams. That way I always know who is calling and if I shall pick it up or not
