Ding-ding-ding! EVO 4G LTE owners, the update you've been waiting for is ready. v1.22.651.3 of the software is rolling out starting today, July 11th, and according to Sprint fixes a whole array of bugs. The most important aspect of the update has to do with Google Wallet which has been broken since pretty much day one of the release. Other changes include improvements to Wi-Fi connectivity, playback of sideloaded videos, the crashing gallery app, calendar reminders, random power cycling, and more.
Fire up your engines by going to Settings > System updates > HTC software update if you're running stock or wait for your favorite custom ROM developer (my personal choice is flipz of Fresh ROM) to merge the changes and provide an update you can flash.
