It comes as no surprise\u2014rumors about an Amazon MP3 app for BlackBerry first hit the Web back in September and leaked Research In Motion (RIM) documents have since confirmed the app's eventual arrival\u2014but BlackBerry-maker RIM and Amazon.com today officially announced a beta version of a brand new Amazon MP3 for BlackBerry smartphones application.Amazon MP3 for BlackBerry Smartphones Icon\n\nAn on-device iTunes music store of sorts for BlackBerry smartphone users, Amazon MP3 for BlackBerry aims to give users on-the-go access to all of their favorite music and musicians. The app's not the first media application of its type\u2014think: 7Digital--but none of the existing apps\/services have the name recognition or user base of Amazon.com. Amazon.com shopping and Kindle apps are also available for BlackBerry.\n\n\nAmazon MP3 for BlackBerry lets users search Amazon music by what's popular, what is new and via genre. It allows for 30-second song previews before purchases. The app works over Wi-Fi and cellular networks. And it highlights daily free-song and album deals. The majority of songs seem to be priced between $0.99 and $1.29.\n\n\nThe app requires 610KB of application memory, so you'll need a media card if you're using a BlackBerry with no built-in storage, and it only works on BlackBerrys running RIM's BlackBerry 5 OS or higher.\nAmazon MP3 for BlackBerry Album Search Screen\n\nI haven't spent too much time with the app yet, beyond downloading a couple of songs, one free, and browsing a bit. But the app's UI looks a lot like RIM's BlackBerry App World\u2014which is a good thing. And it integrates nicely with your BlackBerry media application so you can quickly and easily jump from the Amazon app to your on-device music collection.\n\n\nThe Amazon MP3 app is a welcome addition to the BlackBerry platform, and I'm a frequent Amazon.com buyer, so I can see getting quite a bit of user out of this new software.\n\n\nDownload the application for free via RIM's BlackBerry App World mobile software shop.\n\n\nFor more details on Amazon MP3 for BlackBerry smartphones, visit RIM's website or pop on over to the application user guide.\n\n\nAS\n\n\n\n\n\n Al Sacco covers Mobile and Wireless for CIO.com.
