Remember the Xperia Hallon (MT15) we covered a couple of posts back? According to reliable sources working for Sony Ericsson this particular model will be officialy called the Xperia Neo. The unit which resembles the Vivaz was at first thought to be a Vivaz 2 but the company apparently had other things in mind, making it an Android smartphone on the Xperia line. This will be the third Xperia model to be launched this year with the Xperia Arc leading the way followed by the Xperia Play.
