Sony Ericsson XperiaWe'd like to say we're excited at the news that Sony Ericsson on Twitter confirmed "that the upgrade to Android 2.1 [for the Xperia X10] is due for release before the end of September this year."

OK, it's not that we're not excited, it's just that it's not new.  It was way back in June that SE announced a change to the Xperia upgrade timeline, from early Q4 to late Q3. As September is the last month in the third quarter, it looks like we're still on that schedule.

Hang in there, folks. Your phones will be upgraded to an operating system that's not the newest in the next month or so. In the meantime, you can check out our latest (and second) hands-on with the X10 for AT&T. [Twitter via Engadget]
