Almost a year after first debuting its cloud-based music service, Amazon released an iPhone version of the app today that provides access to most of the features offered in the Android and desktop versions. Not surprisingly, the ability to buy music from directly within the app is missing. Otherwise, you will be able to get access to all the music stored in your Amazon Cloud Drive and features such as creating and editing playlists, downloading for offline listening, and streaming over Bluetooth.

As noted in Amazon’s full press release below, on top of the automatic free 5GB of storage, it will offer a launch promotion providing “those who purchase any storage plan will receive unlimited space for MP3 and AAC (.m4a) music files at no additional cost.”
