Samsung A737 ringtones?

your mp3 ringtone files cannot be anymore than 300kb in order to be used freely as a ringtone on your NEWLY bought phone. by taking the original mp3 song and making it into 20-25 secs ringtones, you need to have a program (ringtones converter) that would allow you to edit your mp3's on your pc. just make sure to save the file to no more than 300kb so that it can be used as a ringtone and than transferred it through bluetooth. hope this help!
