Well that didn’t take long. Just yesterday we saw Sony prepping some Jelly Bean updates for Xperia T devices, and today they’ve officially started rolling out. The update that’s been hitting devices matches what was on the original website, so it looks legit. As of right now, the update is confirmed live in just the Netherlands, but it’s bound to pop up on other parts of the globe. Let us know in the comments if you’re getting your taste of Jelly Bean on your device.
