Ah, the good ol' voicemail softkey issue. I haven't had this one in ages. Fixing this is pretty simple:

Open a registry editor on your device and navigate to HKEY_CURRENT_USER/System/State/Messages/vmail

If you click on vmail, you should see a value in the window on the bottom of your screen; something that says VMailNumber. This should be your phone number (1234567890). If there's a different value, click on it and replace it with your phone number.

In my case, the key didn't even exist for some reason, so I had to create it. If that's the situation for you, just do this:

Click edit
New String Value
Enter VMailNumber (instead of new value 1 or whatever) and your phone number in the other field
Click ok

This was on the old forum, but the URL that I had linked to previously (from 2006) no longer worked.
