The Xperia X10, one of the big mindshare-grabbing devices of the smartphone world, made us wait a cool six months between its November announcement and wide retail availability in April. One of the secret hopes while all that waiting was going on was that perhaps SE would surprise us and upgrade the dusty old Android 1.6 base installation to a fresh and creamy Eclair (2.1) or even a frosty Froyo (2.2) treat shortly after launch. Time to lay those dreams to rest, dear friends, as Sony Ericsson has come with an official schedule for upgrading the firmware on the Xperia X10 and its X10 mini and X10 mini pro siblings, which places the Android 2.1 delivery in the fourth quarter of 2010 -- and knowing the company that probably means closer to Christmas than Halloween. All we can say is you'd better really like that UX platform a great deal, because it'll be the only thing you'll be seeing for quite a while on Sony Ericsson's Googlephones.
