Recently, I traveled to Seoul from Hong Kong. I rented a mobile modem from Vison Data. That costed HKD$60 per day and HKD$1000 as the deposit. This is quite reasonable. Moreover, the process is convenient. I booked the modem online, and then you can pay the rent fee and deposit into their bank account or pay the money in their office. Finally, I picked the modem from their office the day before our trip. Of course you can pay $20 for express post. Then the modem will be delivered to your home.

For speed, that is our reasonable too. 0.97 Mbps for download and 0.43 Mbps for upload.

Lastly, I wish to talk the return process. That is simple, you need to pick back the modem to their office before the second day of your return. Of course you can pay $20 for express post too. Then they will give your a cash cheque to you.

I tried to add a button which will jump a Navigation Control Screen after it clicked. But I ran the application, after the button is clicked, I got this error, 'Push segues can only be used when the source controller is managed by an instance of UINavigationController.'' By try and error, I found that is because the button cannot use "Push" action, you need to use modal action. Then that will work!

During recent Years,"Social Media" is a popular term in the marketing world. A number of people have asked me what is "Social Media Marketing". Social Media is a good tool for marketing. It helps to spread out your name from your friends to their friends, then from their friends' to their friends' friends etc.
You need other good tools. You still need a website. There is a limited information in social media. You need a website to put the detailed information. Moreover, a number of people are still using search engine. You still need a website for search engines to do indexing. Lastly, you need a website to build your corporate image! Please do not forget the old good tool!

Last week, I did my supermarket shopping in Woolworth. I found there is a section for Google Play - Gift Card. That is a good sign for our Android Developer. Therefore, the users do not need a credit card anymore to buy the apps in Google Play. That is more easier to buy apps!

I spotted two new features. Firstly, there is the new multitasking UI. In older version, you can see the icons of the running apps. This version you can see the screen shots by pressing menu button. And then just press the screen shot, you can switch the apps.Well, that is in android world for long time.....

The second one is a bit annoying. It will authenticate the connection cable. It will reject all non-authorized cable. My one is non-apple one, I cannot use it to charge my ipad anymore/
