Newly advanced search filters allow you to search for a specific item and you can arrange to have a reminder go off in your calendar when a listing is about to end. You can also receive real-time notifications when a new bid comes in on a certain item, and when you've won or lost an auction. If you are selling an item, you can use a photo taken with the camera on your BlackBerry to help illustrate what you have up for bids. And if you want to share a listing with a fellow BlackBerry user, the app allows you to do this via BBM in real time.
The eBay for BlackBerry app is a free download from BlackBerry App World and is available for those rocking a 'Berry running 4.5.0 OS or higher. If you've seen the Android or Apple iPhone eBay app, you will be able to tell that the UI is not quite as polished on the BlackBerry version, but it does get the job done in a workmanlike fashion which, after all, is what the current line of BlackBerry is all about.
