It’s about a month and a half since the Chinese version of iPhone was released.

Now we can see ads everywhere.

According to the news last week (, the Chinese version of iPhone sales quantity reached 100,000 in total. But compared with population ratio, kind of moderate growth??

As I wrote “Next time is about gray-market iPhones” in the last post, I guess I got to mention something about it.
Shuihuo in Chinese, translated gray-market in English. Sounds suspicious, though, it seems like they are not always fake. They also include genuine iPhone of other countries. But there are also fake ones.
Well then, foreign versions of iPhone that I saw.
1, US version. Was on sale. Um… I thought US version is not SIM free…?
2, Hong Kong version. Also on sale. Maybe the largest in number. This one is SIM free and expensive than US version.
3, Taiwan version. A sales attendant recommended me this one when I was looking for a dual SIM cell terminal. SIM free and dual SIM. Sounded really nice, but I thought that one was sold too cheap and bit suspicious, and I already have iPod touch, so…I just passed it up.
4, Japanese version. I’m not sure if I should include this one..It was not on sale. I just saw a Japanese using it.

By the way, recently I see ads of China Mobile OPhone very often.

Long time no see, again?

In the last post, I’ve mentioned that we’ve applied ‘DB Tracklayer for MySQL with iphone’ to the Apple’s application review,
and one day, without any notice, it was released ‘for Sale’.
We made it, release!

So, I’m gonna highlight some selling points of DB tracklayer.

To put it simply, it is MySQL client application for DBA.
I’ll list main features below.

  • Features for MySQL
  • Can connect to MySQL servers to browse and edit DB structures or data
    • DB: list
    • Table: list, structure, data
    • View: structure
    • Procedure/Function: structure
    • Trigger: structure
    • Event: structure
  • Display various information of MySQL without inputting SQL
    • Server information
    • System variables
    • Status
    • User connection
    • User privileges
    • Log (available when outputting log to a table on 5.1)
  • If you are familiar with creating SQL sentences, you can execute almost all SQL sentences with SQL editor
    • Has a little assist function for input
    • Has lists that cover almost all keywords
  • Features for iPhone
  • Implements multi column grid control system, which standard development environments don’t have.
  • Customized Mac version MySQL Connector for cocoa touch

Selling points are like this.

It’s kind of self-applause…, but the actual application that we’ve made is really useful than I’ve expected. I use it to check Variables and Status even when I’m using the PC.
And it’s really nice that we can easily check general_log and slow_query_log.
Well, talking of browsing information such as Table data, there are other applications for iPhone, and maybe it’s better to see on… than on iPhone, right?

Any MySQL DBAs, who have iPhone or iPod touch, I really recommend you to try this.
