Sprint and HTC began issuing the update for the EVO 4G today. According to Sprint, the new software version is 1.47.651.1. There are three issues being addressed with this software update. Sprint says the update:
1. Improvements to Wi-Fi performance
2. Exchange Active Sync improvements, including fix to issues with new account setup, PIN policy usage and Exchange Calendar 2010 Sync, and
3. Addresses Facebook sync issue which can improve battery performance
Customers will be notified via an alert when the update becomes available to them. However, users can also manually search for it under the Settings>Software Updates>HTC Software updates on their device. Sprint said the update will be pushed out for the next several days, so it may not be available to all users immediately. The update can be downloaded via 3G or Wi-Fi. (Oddly, Sprint doesn't say that it can be downloaded via WiMax.)
Be careful, though. According to CrunchGear, some readers are saying the update bricked their EVO 4Gs. CrunchGear notes, "While the vast majority of this group admits that their handsets were rooted (read: hacked for customization’s sake), some are alleging that their EVOs were daisy-fresh factory configured units."
These users all saw a second update appear for their devices after the first, and clicked on that second update, which led to the bricked devices. If you've rooted your EVO 4G and still want to update it with the new firmware, be sure to only update once. Sprint has yet to respond to bricked EVO 4G reports.
