I just installed the new Yahoo! Go for the 8320 a few days ago. Everything was working fine until I go a connection error e33 in Yahoo! Go. After uninstalling and re-installing Go about 10 times I noticed that it finally worked when the 8320 was in the lower case uma mode. Once it changed to the upper case UMA the Yahoo! Go failed to connect. I wrote a letter to Yahoo to see if they know anything. I just decided to uninstall Yahoo! Go until I hear something to resolve this issue. When it worked it was pretty cool.
