Judging from our overflowing inbox, it looks like most of you have noticed that the Android 2.3 update for the HTC EVO 4G on Sprint is now available, just like Sprint said it would be. You're getting system version 4.22.651.2, and it's a whopping 109.21 megabytes. Not surprising, but be forewarned.
So what do you get? Judging from our hands-on with an earlier leaked build, you're not going to really notice too many differences, at least visually. Sense is Sense. But you get all of the new APIs and improvements in Android 2.3, plus we figure HTC's thrown in a bugfix or two.
If you haven't snagged the update yet, go to Menu/Settings/System updates/HTC software Update to pull it down manually.
