There's a fresh breeze going through HTC HQ at the moment. The company has opened up ROM updates to almost everyone. I say "almost", because you still need your device's serial number to download the updates, but that's a heck of a lot bet…

えーっと、DXHG4にアップデートすると、CEOS 5.2.20270 (build 20270 AKU1.3.1)になると思います。実機もってる方は確認してみてください ということで、見てみたら、一番新しいっすね〜！
