Sony Ericsson today is sending out e-mails reminding folks (or chaps, since the e-mail we received was sent to our UK operation) that it's shutting down its Sony Ericcson Sync service on Dec. 29. The good news, of course, is that you can (and really should) sync all the same stuff with your Google account, including your contacts and calendars, along with, well, every thing else Android does extremely well.
So, you've got a couple days left to get it down. SE's worked up some instructions to ease the transition. Give 'em a look.
