Carriers are continuing to gradually push out updates for the Xperia Series. The latest update is for any X10 Mini Pro on Three, the update is available via Sony Ericsson’s Update Software. The update isn’t available OTA as usual, but you may receive a notification telling you there is an update available. I believe this is the last update that needed to be pushed out, I could be wrong, if so let me know in the comments below.
If that is the last, we can all rest easy knowing that you won’t have to worry about any more major updates.
