How do I change the notification tone under 2.3 Gingerbread? It seems like I have to use the boring ones that came with my Samsung Galaxy S 2? Another thing is I can't find any apps that would allow me to use ringtone to set alert,alarm for appointment or as a reminder. Again, I am stuck by using the boring default ones. I came from Symbian OS this is my first experience in Android. Thanks in advance.
