For many Windows Mobile users, threaded SMS long had been the Bigfoot of the mobile operating system. You were pretty sure it was out there, you had seen snippets of it, but you'd never actually seen it.
But say you just updated your Blackjack II or your Motorola Q9h to 6.1, and you just don't like having your text messages look like instant message conversations (why, we'll never understand). The enterprising souls over at MoDaCo have you covered.
It involves a wee bit of registry hackery (and has also been neatly wrapped into a cab file), and reportedly works on touchscreen and non-touchscreen devices.
If threaded SMS on WM6.1 just isn't your thing, check out the solution here. And as always, backup your device first.
