Back in April 2009, Research in Motion launched BlackBerry App World, their online app serving portal accessible directly from a Blackberry handset. Unless you were an Australian, of course. In December last year, RIM finally launched the Australian version of App World, but despite the fact that the payment method of choice was the global Paypal, paid apps weren't supported down under. Until now, that is.
Provided you have a PayPal account and a relatively recent Blackberry phone, you can now purchase applications on your handset. Huzzah!
