Can't put it more plainly than that. According to this little tidbit that just hit our inbox, it looks like the Sprint HTC EVO 4G -- the first 4.3-inch Android smartphone, as well as the first with 4G Wimax -- could find itself with a an Android 2.3 update -- that's Gingerbread, folks. Starting June 3, you'll be able to manually update. Three days later, if you haven't already requested the update, your phone will ask if you want to update. (Hint: Say yes.)
If this is on the level, it looks like we'll be getting software version 4.22.651.2. And in addition to all of the Gingerbread fixes, you'll see fixes for the infamous SMS bug, a tweak to the Spanish translation in SMS, gmail syncing and that long-annoying bug where batteries just refuse to charge. (Oh, hai, Dieter.)
None of this is official quite yet, and updates like this never hit all at one time. But we've got a good feeling we'll see Gingerbread on the EVO 4G sooner rather than later.
