When I was first sent the link to this news, I honestly thought I was about to get Rickroll’d, but that was not the case. Sony Ericsson are actually going to update the Xperia X10 (only generic handsets currently) to Android 2.3.3 between Q2 and Q3, which isn’t bad seeing as though Sony Ericsson said it wasn’t possible to go past 2.1. SE have now said that Gingerbread was their main focus and working with other devices launching this year lead them to be able to port 2.3.3 over to the X10. They also confirmed that no more work will be done on the X10 once the 2.3.3 goes through, though we’ve heard that story before. The update will only be available through SE’s PC-based updating software as it can’t be done OTA.
None of the other last-gen Xperia devices will receive the update and we’re currently unsure whether or not carrier branded X10s (ie. most handsets sold in Australia) will receive the update. If carriers want to keep their customers happy, I’m thinking they’ll be pushing out the update ASAP, so early 2012 going by what we’ve seen in the past.
