We’ve been looking for a good threaded SMS option, one that doesn’t require registry hacking to work. There is always Textr, but for most people, the trial doesn’t work, and the company is completely unresponsive to support queries.

Smartphone Thoughts is reporting that Birdsoft has released a threaded SMS client for Smartphone/Standard called Extreme Text. It looks to be a decent solution for those who dislike the way that Windows Mobile treats SMS. If this is of interest to you, get the trial, and if you like it, the program costs a reasonable $13.
