It's been a busy day for T-Mobile and Windows Phone updates. First we had the Dell Venue Pro update going through and now we are getting word that the HD7 is getting an update of their own.
According to AtomicAgeZombie, who tipped us on this, the updates deal with firmware and radio software. The old firmware (2250.09.12001.531) is updated to version 2250.21.30102.531. The old radio version (5.51.09.11a_22.31.50.09U) is updated to the new radio version 5.65.09.25a_18.104.22.168U.
T-Mobile HD7 owners should get the customary "There's an Update available" message on thei Windows Phone. If you miss it, simply connect to your Zune Desktop and check for updates under the Settings.
If you've already updated, feel free to chime in on the process and what effect the changes have in our comments section.
Thanks goes out to AtomicAgeZombie for the tip and update info!
