Just before the weekend RIM finally brought their eBay for BlackBerry app out of the Beta Zone and on to App World. RIM introduced this new version of eBay for BlackBerry in September with BlackBerry OS 7.0 support, selling features, and more. It adds the ability to post your winnings on BBM along with sharing your listings and better searching. It went through a few updates in App World over the months and is now up for anybody to grab in App World. Users in App World reviews seem to be complaining that the previous version did many things better but hopefully that is resolved by RIM with bug fix updates.
You can pick up version 2.0 of eBay for BlackBerry in App World
