Xperia ray (ST18i) : GB ---> ICS

I use Xperia ray (ST18i).
Xperia ray has multiple type of versions.
I know JP version, US, North europa, Asia, and china.

And, I know JP version is one of the worst version for new release because of economic and political reason. So, I bought from hong kong. However, china version also had different meaning of political reason. I thought it is good for SIM free version. However, the bad point is that the phone cannot access to google account even if it is android phone. So, i decided to flash the rom from 2.3 to 4.0. I used official rom for north europa version. Many sites explain how to change rom. So, I don't do this. This time, I got friend's help. Because, the rom flashing too is provided for Windows or Linux. I have linux machines but it has many risks for flashing rom with linux machine.

I thought that I should wait for real release for my phone. The first release was last april for US version. And, I waited almost 1 month. However, it could not get new release. This meaning is that the version has more complex implementation than common release. This meaning is the version of ICS also cannot access to GooglePlay, google map with my account. youtube with my account, etc. So, I changed....

The largest change is setting up menue. For the GB users, I think ICS's interface of OS setting up is version down. It is more difficult to use there menue. However, most of android is not so difference. I can use many think as GB. The response quality is not so difference. I don't know why but I think the resolution for width is larger than before rom. The using way, I feel this version of rom is wider than before. On the before rom, my phone could not fined my mp3 files from my sd card.

Now, I can use google play, gmail, gtalk, youtube, map, navi and etc... This change was so big for my smartphone life.

The bad thing is camera function. The quality is almost same. But, the UI became worth than before.

And, I set up the AP. First time, I added AP information. And, it was working when the time. After that, I wanted change the MMS information. Then suddenly my phone  could not connect to 3G network. I didn't find this problem. Because, I uses wifi on may time in my house. When I went to biking, I found this problem.  The solution of this problem is simple. 1. you need to remove previous setting. 2. Create new AP setting up. And put correct infomation.

Bicycle insurance in japan

Long time, I was considering about bicycle insurance.

Many japanese are not consider about insurance for bicycle in japan. Because japan is weak country for insurance.

Many people considered about when they are attacked by car. They didn't have an idea what they may be going to be individual at fault. However, road bikes are faster than my MTB. And, many of city bikes do not turn on a head light after sunset. The old person has also no idea what the bicycles can ride so fast as 50cc motar bike. Then they easy enter in front of bicycles. Such kind of accident is not few in japan. And, the worst case of such accident, the road bike rider needed to pay 40 millions yen to attacked person.

Bicycle ride's bad manner have begun to social issues. Some bicycle riders do not follow the traffic lights or traffic signs. In such background, sometime, I have risks what I will be attacked by such bicycle riders when I ride my MTB. However, as above reason, many riders have no insurance for r…

SSID in japanese?

Usually, we don't use japanese for setting to computer. Because, japaese needs at least two byte. Usually, many computer systems are designed for one byte. So, to use japanese in the system setting was not common way. If he is usual engineer then he will not set japanese for the setting to SSID. I was not do such a thing. Today, i read a tweet written by my friend. He wrote that he could see the japanese ssid from his house. I was really  suprized when i read it. So, I asked prof. Google about this ssid expression in japanese. So, it is  exist.Now, I had no wireless devces for trying it. But,it is so intersting thing for me.

TokyoWalking : Tram @Arakawa-Line

End of last year, I went to cycling to Ikebukuro. Ikebukuro is one of the main city on Yamanote-line (loop line) It is north area of Tokyo (loop-line).

Basically, most rail lines on mid-tokyo are as subway or elevated railway. So, it made my so surprising, when I saw it. 
This is tram in tokyo. I did not know that tokyo also has a tram.

Following photo is another tram station.

I saw several tram on the railway. Most of them are painted with different line (maybe...) This tram is named Toden-Arakawa-Line. This line is for Waseda University. I could not take the tram, becase I rode my bicycle. However, I will take the tram on some day.

Following river is River, Kanda. The river is used on some old japanese song.
