My unanswered calls are picked up by the Telecom messaging system - a live person in a call centre.  Messages are then sent to me in SMS format, like a pager.

As I've flashed or upgraded or hacked or whatever I did to WM 6.1, SMS messages are now threaded.  All of my call centre messages come up in one big looooong thread.  I have to double tap the idividual message within the thread then delete it. 

It's not a huge issue, just a little inconvenient.  I can live with it but I was wondering if anyone had some kind of alternative.  Threaded SMS doesn't appear to be something I can toggle - it's always on and to be honest I do like the threads.  Something I've missed since giving up the Palm Treo years ago.
