If firmware hacking is your thing, you might want to forego that previously leaked Windows Mobile 6.0 Professional ROM, and go for broke with threaded SMS text messages. This cooked ROM is GPS enabled, so you’ll get the same benefits as the pre-release ROM, but with the added benefit of threaded text messages.
no2chem from PPCGeeks forum cooked up this ROM and has made it available for brave Sprint Mogul owners itching to try out threaded text messaging. You can grab the ROM here.
As with all firmware modifications, you’ll want to get nice and intimate with the flashing procedures before you dive in. All data will be wiped from the handset, so make sure you back up your contacts and what-not prior to applying this ROM update. Good luck, and let us know how you like it!
