Xperia X10

You've got to feel for Xperia X10 owners. They spent most of 2010 stuck on Android 1.6, and so far 2011 has brought the news that the device will never get an official update to Android 2.2 Froyo.

Some good news has emerged recently, however, with the publication of some new source code for the X10, X10 Mini and X8 on Sony Ericsson's Developer World site. The code for the unreleased version 2.1.A.0.390, based on Android 2.1, includes an updated multi-touch driver allowing for dual-touch support, according to the resourceful people at xda-developers. This would be a first for the X10 series, as current touchscreen drivers for these phones only support pinch-to-zoom rather than full multi-touch.

Unfortunately, since the X10's bootloader is locked, X10 owners will have to wait for Sony (and possibly their carrier) to approve this update before they can get it on their phones. Despite months of effort, the Android community has not yet succeeded in getting custom firmware loaded onto the X10. [xda-developers]
