One of the common issues that BlackBerry users face on their devices is the missing BlackBerry App World icon on the screen after an update.
Apparently, the problem appears with several native Research In Motion apps, but there are several ways to fix it.
Users who have had a beta version of the application installed on their devices are often asked to remove the old app when upgrading to an official version, in order to avoid such problems.
Those who haven’t, however, are more likely to experience these issues, but no specific information about their cause has been provided by RIM.
Yet everything seems to emerge when the new version of the app is installed over the old version without removing it first.
On devices running Blackberry OS 6 earlier than 22.214.171.1246, where the icon does not appear, users should try to remove BlackBerry App World installed on their phones and reinstall BlackBerry App World 126.96.36.199 instead, suggests RIM.
To do this, they need to launch the BlackBerry browser on their smartphone, go to http://mobileapps.blackberry.com/devicesoftware/entry.do?code=appworld3, download the file, and restart the handset when prompted.
On BlackBerry 6 OS versions 188.8.131.526 and above, users are advised to download and install the latest version of BlackBerry App World (currently 184.108.40.206), provided the icon does not appear on the screen reception.
It is also possible that the icon does not appear if the device was not restarted after installing BlackBerry App World. In this case, users need to turn off the device, remove the battery, put it back in the phone, and turn it on.
Another possible explanation for the missing icon is the fact that it is hidden. To resolve this issue, press the BlackBerry menu button on the Home screen, select “Show All” and make sure the screen is in the Home screen of the “All” panel.
Users should do the same for each folder, provided the icon still does not appear. If they find it in a folder, select it, press the BlackBerry menu button and click “Hide”, as this will deselect the hide setting.
If these steps don’t work, users can also try another solution. They should remove BlackBerry App World from their smartphones by going to Device> Application management> BlackBerry App World. Press the BB button when and select Delete.
According to blackberryos, users must also erase pushed content from their BlackBerry’s browser. Launch the browser, click on the BB button and go to Options, then go to “Clear browsing data”. Select Push Content and press “Erase Now”.
As soon as this is done, restart the telephone and reinstall BlackBerry App World as for the first time. The application can be downloaded via the browser or live from the official RIM portal, via this link.
The app will not ask for a restart after installation is complete and the BlackBerry app icon should display on the Home screen.
Apparently the same can be done for other natives applications from RIM that exhibit similar behavior, including Twitter for BlackBerry and Facebook for BlackBerry.
