Currently using a Docomo P906i with the K810i as backup.
But my new W980i is arriving soon~~~~ I just hope I don't brick it. I have a tendency to brick a lot of my phones from owning it less than 1 hour because my curiosity~~~. Although I was pretty good with the K810i..... I haven't bricked it yet lol.... I think I'm jinxing myself already haha~~
