au KDDI is pushing out an update to IS12T owners in Japan today. So find a PC and plug in. I'm not sure if this is a rolling update. Based on past updates, it should be released at the same time across the country.
Currently I'm still going through the process of updating. I'll edit this post when I get more information about the update.
I got excited and forgot to look at the update information at the beginning. (^-^;; I'll look at what software was updated first.
More to come
I just finished the uipdate and only got time to glance at the device information. I was able to quickly gleen that device firmare had been updated from 5008.1907.1210.0750 to 5008.1907.1218.0790. The wireless firmware was also updated from 1.2.07.50 to 1.2.07.90. I didn't have a lot of time before another update notice came.
Right after finishing my first update, a second update was waiting immediately after. I didn't even have time to unplug. The second update is the 7.10.8107.79 update. I recommend that IS12T owners should remember to plug their phones into their PC when they have the chance.
The update time took roughly 10 minutes, and it consists of two updates. Please, don't unplug until both updates are complete.
