Good news for those of you with the LTE version of the Sony Xperia ion (LT28i), the Android 4.0.4 ice Cream Sandwich update has started to roll out. The new firmware will update you to version number 6.1.E.1.19. From what we can gather the update has started to roll out in Hong Kong and Taiwan, so we would expect it to hit other regions shortly. At this stage we do not know if there are any firmware differences between this version of ICS and that currently on the Xperia S and Xperia P.
