We'd heard rumblings about this update last week, but Sprint has started the official rollout today. Tipping the scales at 21.43 MB, the update is rumored to fix Wi-Fi connectivity issues (including the possibility of enablling EVO's 802.11n support) and various other bugs. I don't know about you, but I join with every other tech journalist out there in hoping that battery life improves as a result of the update. As it stands, I'm charging my unit twice a day - and that's without Wi-Fi, 4G, Mobile Hotspot, or any other battery chomping service enabled.
At any rate, we'll find out soon enough. EVO users, go get your download on, and hit the comments with your findings!
