A few spy pictures, published online, reveal a new small slider that is supposed to expand the Sony Ericsson line. There is no additional information available at the moment, and everything else is just speculations. However, it seems it will run the latest software, used in other new models (such as the W910 which is displayed, K850, W890 and others). The model number of this small slider is yet unknown and the SE 123 is just what the manufacturer uses for its prototype phones.
