You could try a smaller file size, say, less than 300kb. Sometimes the carrier firmware limits the size of the ring tones you can utilize on a particular handset. Also, if you can find mac software to adjust the bit rate down a little, that might make the same file small enough to work on your Sammy. FWIW, on a PC I use Audacity for tweaking ring tones.
I have a Samsung SCH-700, and i was told of a way to transfer music via bluetooth to my phone. I'm trying to create my own ringtones. However, every time I try to transfer a file it says, "device is saying it will not accept this file type." When I tell it to download anyway, it gives me an error message. Is this phone just not capable of doing what I'm trying to do? Please help.
