Android Central

We noticed just shy of a week ago that some users were reporting that an update was available for their AT&T Xperia Ion. AT&T has spilled the beans now, and announced officially that the Ion has an Ice Cream Sandwich update ready to go. Along with the entire host of usual Android 4.0 improvements such as an improved lock screen, redone browser and new home screen folders, AT&T notes that the update will "provide faster Mobile Hotspot and Wi-Fi speeds" on the device.

This update won't be coming OTA (Over the Air) to your device, so you're stuck downloading Sony's PC companion software to download and apply the update (seriously, just push it OTA please). Check out the source links below to see the official statement from AT&T, as well as the Sony support page to hep you setup the software for the update.
