I am a new 8330 owner from VZ. My Curve has an 8G card in it.
I just downloaded BB app world, clicked the icon, and looked at some of the 12 featured apps. I closed the app, then opened it a few minutes later. The app is now locked and won't repond to any command. Menu bar will not appear either.
I turned the Curve off, reopened the app, and the same locked situation is there.
