Samsung SCH-A650

Hello. I'm new here and am a new user of the A650. I know this may be a rather lame question but I have no idea how the "get it now" feature works. I was attempting to download ringtones and am curious as to how to do this..do you have to download programs on get it now to get ringtones, wallpaper etc?

If so, which is best?

I've looked on different websites that offer ringtones..has anyone had any luck with finding a site that offers a650 tones? It would be nice to find a site to download from rather than paying airtime while you browse for a ringtone.

Thanks in advance!
