Nah, I had this same problem with .234 as well. It's documented on "other" sites as to the fix. I had to "C:\Program Files\Common Files\Research In Motion\Shared\Loader Files\9000-v126.96.36.199_P188.8.131.52\java" and delete the visual voicemail files. I don't remember them off hand. Something like net_rim_bb_visual or net_rim_bb_vv.... Do a search and you should find step by step instructions.
Once I did that and rebooted the Visual voicemail icon was gone from the menu and the icon reappeared.
