Unfortunately there is no cab file for the threaded SMS from WM6.1. The threaded SMS is embedded so deep in ROM and is tied into so many different parts of the phone such as Outlook and the Phone app that it would be impossible to create just a cab file for it.

Personally I find that hard to believe though because if you install Palm Threaded SMS it takes over the SMS app 100% and removes the original SMS app that was on the phone and ties into Outlook just like the original SMS app. The only problem is it also has the same problem as codysms where the keyboard covers the input field.
