Just as it did earlier this year here in the States, Amazon has now quietly announced that it's brought some HTML5 tweaks to its UK-based MP3 store in order to make it more friendly with iDevices. Thanks to these under-the-hood enhancements, iPhone, iPad and iPod touch users in the United Kingdom can now have access to more options within the web version of Amazon's music shop -- you know, things like downloading and streaming songs. Naturally, once you've purchased some tunes, they'll automatically be added to the Cloud Player, where they can then be played from any other compatible device (e.g. Sonos systems or an Android tablet / smartphone). You can check out the optimized Amazon MP3 hub over at the source below.
