Sony Ericsson Xperia X21 Mobile

Sony Ericsson  Xperia X21 Mobile: This is the Sony Ericsson Xperia X21, a device created by Long-Nong Huang and a handset that uses a 4 inch Reality Display, plus 1GHz  CPU.
Other details are not known, but the form factor and design sure remind me a bit of the  Nokia 5800 XpressMusic.
