A new firmware version (6.1.E.2.68 ) for the LTE Sony Xperia ion (LT28i) is now rolling out in China and Hong Kong. This firmware is still a branch of Android 4.0.4 Ice Cream Sandwich, however we don’t know what specific improvements this firmware brings over the preceding version. It is currently only available for the LTE SKU (LT28i) of the Xperia ion, so HSPA+ owners (LT28h) will have to wait. If anyone has updated to this version, please chime in with your comments below.
