Does anyone else have problems with the BB App World disappearing? I have installed it three times on my BB and it shows up when I press my menu button. The next time I go to look for an app on my BB I have to reinstall App World. I've only had the BB for a week and this is getting to be an aggravation.
After doing more research this is a common problem right now. See http://supportforums.blackberry.com/t5/BlackBerry-App-World-General/BB-App-World-keeps-disappearing-... as it will point you to KB article KB20185 which states that this an issue that RIM is working on.
