Android mobile phones comes with some good ringtones . I extracted the stock android ringtones from my Samsung galaxy ace s5830 so that you can use them in your non android phone. All these files are in .ogg format, you can play them in your computer using vlc mediaplayer or something else.
The .rar file includes the following:
- Phone Ringtones
- Notification ringtones
- Alarm tones
These files are taken out by using Airdroid.. give it a try.
