A few weeks back, Sony Ericsson released a firmware update for the Sony Ericsson Xperia X2. This update was dubbed the MR1 update, which added video calling support and and FM radio support. At the time, another update, the MR2 was promised which has now been released. Again, this update improves performance of the handset and usability but, the biggest part of the update, is that it brings Windows Mobile 6.5.3 to the X2. To upgrade, you’ll need to use the Sony Ericsson Update Service. If the update isn’t showing, check back in a few hours, as it’s being rolled out throughout various regions at a different speed.
