BlackBerry users in Australia and New Zealand now have something to smile about. RIM has officially launched BlackBerry App World, (its very own version of the App Store) in Australia and New Zealand. This is important for obvious reasons. The most important aspect of any powerful phone these days are the apps.

Maybe this will get Blackberry sales up in the land down under while the iPhone goes on walkabout. You never know. Hey at least you’ve learned something new about that part of the world. Something that has nothing to do with Nicole Kidman hailing from there, Mad Max movies, kangaroos or vegemite.

Apple’s AppStore and Nokia’s Ovi Store aren’t the only ones with good stuff. BlackBerry’s APP World also has a few good things. Here’s one. If you do a lot of online shopping, eBay has designed an application for BlackBerry handset users.

It’s a full feature application designed to also accept PayPal payments. It will also allow buyers to search for items and track their status so they can see where they stand in their current bidding war. Users can also schedule auction-related reminders in the BlackBerry calendar. This app is available as a free download from App World.

I am not a big fan of streaming music personally, but in theory services like Slacker sound cool. Rather than buying individual tracks, Slacker lets users create personal radio stations. The service is available for mobile phones and computer users.

Slacker has announced that its application for the Blackberry line of smartphones has now been downloaded a million times via the Blackberry App World. Using the application Blackberry users can listen to personal or programmed radio stations over a wireless network.
