RIM is offering a new service called Concierge for BlackBerry owners. The feature allows users to monitor the applications that have been installed on the handset and is expected to launch near the end of the year. With a dashboard type display, Concierge keeps track of things like the music you have listened to, whom you have tweeted and what products you have purchased on eBay. The service, which is based on the use of widgets, will be integrated into the platform and must be supported by the individual carriers. Speaking of carriers, RIM has also announced that BlackBerry App World will soon support carrier billing which would allow you to pay for apps on your cellphone bill.
