I have a Samsung Solstice, and I downloaded on my phone a ringtone from Zedge.net. I tried putting it as my ringtone but I can't.. I'm very disappointed, because than that was a waste of money to go get it by using the mobile web. My question is why can't I? Because the format is too big? And where can I safely download some ringtones that WILL work for my Samsung Solstice?
