It’s been so long that we almost stopped caring, but HTC and Sprint have come through to deliver a welcome update to the Sprint Touch. Unofficial versions of this firmware have been floating around the web for quite some time, but if you’re the sort that doesn’t like to color outside of the lines, you’ll be happy to know that the official Windows Mobile 6.1 upgrade for the Sprint Touch is now available directly from the HTC website. The changes and enhancements that come along with the WM 6.1 upgrade are old hat by now, but we’d still suggest updating your handset if you have the chance, as you’ll reap the benefits of EV-DO Rev. A, enhanced GPS functionality, an OEM version of Opera, and more. Hit the jump for more info!
