In RIM Blackberry OS 4.6+ there is a new feature - ability to show notification icon in statusbar. Integrated application use it to give quick and informative information for user: Dealler - missed calls, Messages - unread messages etc.
removed dead ImageShack link
Possible use of notification icon:
- missed events
- RSS updates
- object status (ex. weather/app activity/gps signal strength)
- other
I would like to post a howto guide for this feature.
