Gears™ is an extension to the browser application that is designed to provide a richer browsing experience. When you visit a Gears enabled web site and enter information, Gears can store that information on your BlackBerry® device or media card for use during later visits to the web site.
Gears can also help web sites provide customized content to you if you choose to share your location with that web site. Your device does not need to have an internal GPS receiver or be paired with a Bluetooth® enabled GPS receiver to share your location.
The first time you visit a web site that uses Gears, you are prompted to set the permissions for that web site. You can turn off the prompt so that your permissions for the web site are saved. You can change or delete the permissions for Gears-enabled web sites.
