The X10 offers a 4 inch display and is powered with a 1GHz Snapdragon processor under the hood. The 8.1 MP camera is equipped with both face recognition and smile detection, and offers AF and a LED flash. 1GB of internal memory is boosted with a 2GB card in the box, and can be expanded up to 32GB. Of course, the Xperia X10 has the Timescape and Mediascape applications. The former will focus on your social networks while the latter will integrate your music and videos to one place. The press release fails to mention which build of the Android OS the X10 will carry, but earlier speculation was that the phone would launch with Android 1.6 and receive an upgrade to 2.1 by the end of the year. Unfortunately for all of you pinch-to-zoom fans out there, the handset does not support multi-touch.
