About downloading items
BlackBerry App World is designed to prioritize available network connections and automatically chooses an authenticated Wi-Fi® network over a wireless network for downloading items, if both types of networks are available. Downloading items over the wireless network can affect your wireless data usage. Check with your wireless service provider to determine the additional costs that might be associated with downloading and using BlackBerry App World.
You can easily find and open your downloaded items on the My World screen. You can also find downloaded items in the Downloads, Games, or Instant Messaging folders.
