Official fix for unofficial Froyo update for HTC EVO now available
Anyone with the pre-release Froyo firmware (version 3.26.651.3) running on their HTC EVO has been able to unofficially update to the final version (3.26.651.6) for about a week now, and now those who decided to wait it out can legitimize their EVOs with the official Froyo update too.
A 4.17MB maintenance release that puts the EVO "back on the official track" is now available by pressing the Menu button on the phone and tapping Settings -> System updates -> HTC software update -> Check now. Unlike the unofficial fix, this update will not do a clean install of Froyo, so your EVO will not be reset to factory condition.
Some say that many of the bugs and other issues that are affecting users who have either applied the original Froyo OTA update or the leaked version are often solved by a wipe of the system, though, so you may want to consider taking the RUU route if you want to start fresh.
This update resets a few settings back to default, so make sure to skim the battery tips again and adjust whatever suits you.
Thanks to everyone who sent this in!
