Last week, a rumor began swirling by way of BGR regarding a new update that Sprint and HTC would be pushing out OTA to fix several more issues with the HTC EVO 4G. Specifically, WiFi fixes, changes to Exchange ActiveSync behavior, and fixes for Facebook sync features were said to be addressed with this update.
It’s June 28th now, and sure enough that OTA has made its way to EVO 4Gs this morning. The update is versioned 1.47.651.1 and is a meager 21.43MB in size. You can wait for the device to notify you to download the update, or do it manually by heading into Settings > System Updates.
