According to rumors attached to the above photograph, what we are looking at is none other than Sony Ericsson’s Hallon handset. It is widely thought that Sony Ericsson will introduce several high-end handsets at Mobile World Congress in Barcelona this February. The device pictured has a front-facing camera, convex top, and is running an unknown version of Android (some outlets are reporting that the Hallon is running Gingerbread but it is difficult to clearly discern whether we are looking at Android 2.3 or a Sony Ericsson UI skin). The handset also features a top-mounted micro-USB port, similar to the one present on Galaxy S handsets. The Hallon will purportedly bear the model number MT15i; a model number that some have seen in their website user agent logs. With CES and MWC on the horizon, you can expect to see a barrage of new Android handsets from OEMs in the coming days and weeks. Who’s excited?
