If you use BlackBerry’s App World to download applications, updates, and regularly find new content, you’ll be pleased as punch to know that App World 2.0 has just gone live in beta form. App World 2.0 brings a number of enhancements to the app — some much needed — and even some new payment options. For starters, credit cards are now directly supported instead of having to go through PayPal, and RIM has brought along support for carrier billing. In true RIM fashion, however, this is not available now, and RIM won’t say which carriers will support it. Next up is the ability to drill down different top 25 lists, something much needed. There are now top 25 paid, free, and theme sections. Simplifying the entire user experience is BlackBerry ID, something you can probably guess. It’s a device-independent user ID, something separate from PIN mumbo jumbo, and will streamline your purchasing profile, keep track of your downloaded applications, etc. Not much of a finder/gatherer? Lastly there is QR barcode support in the new version of App World, so look for developers to start using barcodes in promotional materials, emails, really anything. It’s available now on RIM’s beta site below for download.
