(Telecompaper) Google announced that Android has passed the milestone of over 1 billion devices activated. The announcement came alongside the unveiling of the latest version of the mobile operating system, Android 4.4 KitKat. While the KitKat brand is owned by Nestle, Google said the use of the name for the latest release of Android was not part of a commercial agreement. "This is not a money-changing-hands kind of deal," John Lagerling, director of Android global partnerships, told the BBC. He said the idea was to do something "fun and unexpected". The agreement with Nestle will also see the launch of a Kitkat chocolate bar in the shape of the Android icon and a contest with Nestle to give away Google Nexus 7 tablets and credits for Google Play, starting 06 September. Further details of the new software will be announced at a later date.
