The HSPA version of the Sony Xperia Ion, Sony LT28h, has received a new ICS firmware, named 6.1.E.3.7. The update should bring performance improvements and probably some bug fixes. It’s still Android 4.0.4 though, so no Jellybean love for now. The changelog is still not published, but it shouldn’t take too long before it is. Note that this is only for the LT28h model, and it’s expected that the LTE variant, the Xperia Ion LT28i will get the update shortly.
