I read alot of people having this problem. I have a v220. The ringtones that came with the phone work fine. But when I try using a ringtone that I transferred through the cable won't work on an incoming call. After trying many different things and nothing worked this is what happened. I deleted the ringtones I added, put them back on. I turned off my phone and turned it back on. Set the ringtones. Now it works. My hubby has the same phone and I couldn't get his to work either. Turn off, turn back on, works. Whataya know! Also, I had a hard time finding a data cable for my phone, I just happened to be looking at the mp3 players at Walmart and there it was, the data cable that fits my phone. Its a Belkin USB 2.0 cable, A to 5-pin mini-B. It doesn't say cell phones on the package, but it works. Hope this helps!
