The first over-the-air software update for Windows Phone 8 is rolling out as we speak, and the first smartphone to get it is the HTC 8X. It brings the OS' build number from 9905 to 10211, takes care of the random reboot issue we wrote about recently, and introduces a handful of new features, along with an anticipated Wi-Fi connectivity tweak.
Long time Windows Phone users can probably guess what Wi-Fi tweak we're talking about. After upgrading, one has the option to have the Wi-Fi radio on their smartphone turned on constantly. Previous WP versions turned it off automatically during stand-by in order to prolong battery life.
And that's pretty much all for now. All that's left is for the new software update to reach all Windows Phone 8 smartphones. We'll keep you posted as soon as we get reports of it landing on other handsets.
