For you who have Blackberry, having App World in your device is like having App Store in your iDevice. It’s essential, irreplaceable. You can download new apps using it, and upgrade them whenever new version coming out.
Unfortunately, things are not as smooth as it can be. If you’re now currently downloading App upgrades from the App World, and the connection suddenly interrupted (or the device suddenly hang or restart), the program’s icon will be disappear, because the App World will already hide it. Thank God, there’s a very easy solution. Just reconnect to the internet, re-download the app from the App World, and voila! All is good, as long as we have access to the App World. As long as we have.
Then, how if, say, the App World itself is gone? In my case, I was upgrading the App World to a brand new version, while suddenly the internet connection is lost. I thought that was a simple matter. I just re-established the internet, and took my device to re-connect to the internet, when I found that the device stated “failed to install the app”. I press “OK”. Then another popup saying “You have to reboot the device”. I press “Reboot Now”. And it’s rebooted. But, as you can tell, the App World icon is gone!
