We don't know exactly what's included, but Sprint's sending out that rumored over-the-air Android software update to HTC EVO 4G devices this morning. It's labeled as version 1.47.651.1, and it's just 21.43MB, so we're guessing it's just mostly bug fixes, but word on the street was that it would "enhance" WiFi, so there's a chance it could enable the EVO's 802.11n support, and we're also hoping for some improved battery life. We'll update you once we see some release notes, but in the meantime let us know how it goes, yeah?
Update: Release notes have been posted, and they're just as expected -- and unfortunately, we still don't have confirmation on whether "improvements to WiFi performance" means 802.11n. Check the full notes after the break.
