networkn: Can you boot into recovery foo?

Brendan: Try wiping the delvik cache in advanced... And also the other cache.

If not you will have to do a wipe/factory reset and load your contacts etc again from gmail.

Okay, will select the "wipe cache partition" option.

I haven't rooted my phone nor flashed non-stock f/w. 

networkn: If this is just a standard phone with no root or custom ROM, then I am suspecting you should remove the external SD card and try again to reboot?

networkn: Might be a warranty call, is it a NZ phone or imported?

networkn: Not a lot of downside, unless you don't have a backup. I can't think of anything else.

lyonrouge: Is there anyone out there with an un-rooted Telecom S II and a Exchange Server 2010 backend that can confirm is SMS Sync (see image) is enabled. I've seen this on a rooted S, but wanting to see if this is a out-of-the-box feature of the S II (third party implemenations come with "challenges").

No backup - but using the Android web marketplace I can reinstall everything. I really should have rooted my phone and installed titanium backup.

Oh well, no big loss assuming a wipe and reset fixes everything.
