Google have released a HTML 5 version of its Googe Music service designed specifically for iOS devices and bypassing Apple’s App Store restrictions. On Twitter the Google Music team said:
Music Beta users – try the new mobile web app for iOS4 and listen to your music on the go: http://music.google.com
Like many other music services its US only but if you do have an account you should be able to browse your Google Music collection and play music in the background. Have any readers got an account? If you have have you tried the web app?
