Official Sony Ericsson XPERIA X2 Windows Mobile 6.5.3 Released
As promised by Sony Ericsson, those that own the XPERIA X2 can now download an update that will give your device Windows Mobile 6.5.3, among other little fixes. To get the update, visit the SE Update website. Depending on your region, the update may not be available yet. If not, head to XDA where they show you how to get it sooner.
Thanks for the tip, Andy.
