We all know that Sony Ericsson will be coming out with an Android 2.1 update for their entire Android XPERIA family of phones - the X10, X10 Mini, and X10 Mini Pro - later this year. This is further supported by this leaked roadmap courtesy of XPERIA X10 blog which outlines the various Android updates that will be released and the new features each one brings with it.
Android 2.1, for example, will introduce 720p video recording with continuous autofocus along with HTML5 support, 5 homescreens, and Facebook/Twitter integration with contacts to the XPERIA X10. As for its pint-sized counterparts, the X10 Mini and X10 Mini Pro, apart from the HTML5 and Facebook/Twitter integration, Android 2.1 will also add Bluetooth 2.1 support and will slightly change the four-corner shortcut navigation system which is a key trademark on both phones. After the Android 2.1 update, there will also be a 2.1x update which will upgrade the proprietary Timescape and Mediscape apps to more modern standards. Unfortunately, this is where it all ends. There’s no mention of Android 2.2 anywhere in the leaked roadmap.
So, unless this is just an outdated file or a singled out page from an even bigger document, it seems that Sony Ericsson has no intentions of releasing an Android 2.2 update for these phones. This isn't confirmed though and we’re certainly hoping it's more of the former than the latter. Unfortunately, this is all the info we have right now, but rest assured, once Sony Ericsson comes out with an official statement addressing this issue, we'll be here to talk about.
