The Old Yahoo Inc. backend for the iPhone Stock app was changed recently and has completely lost the ability to search Japanese stocks in Japanese and display Japanese company names. The only way to add Japanese stocks is the English company name or the stock number which is the only ticker information displayed now. Unless you trade Japanese stocks for a living, nobody remembers them by code number.
In addition to those changes there is now a 20~30 minute lag before Japanese stock market prices are updated. The iPhone Stock app used to update Japanese market info within a minute or so and was very handy. Not anymore.
If this is Verizon’s idea if a stock market app backend for Japan, Apple needs to find a replacement ASAP.
