Finally, I got some free time to upgrade my Samsung Galaxy. But I found I cannot get my Samsung Kies keeps to restarting in my Samsung Galaxy. That sounds some applications are crashed with Kies. I tried to unstall Foursquare. I remember after I installed Foursquare, my phone got some funny problems with Kies. That is not helpful at all. I think I need to format my SD cards.

Android 2.3 added a feature calls Near Field Communications(NFC). Therefore you need to put your phone near a NFC enabled sticker or posters, you can read the message inside the NFC enabled stickers or posters. Please watch this video(9:55) from IntoMobile. There is a demo about it.

We were waiting for Android 2.3 for long time. This week, Google finally released Android 2.3. There are a few key improvements:
- better and faster UI
- a new soft keyboard
- a one-click cut-paste
- More gaming supports
- support WebM and VP8 video.
I think to learn more about it, let us watch the video from Google

I am looking forward to upgrade my Galaxy to 2.3 (if that will be possible :-)!)

I think the most of people know even Skype has released their client for Android, but it does not support Galaxy S. Yes, I know some people told they are using a unofficial 2.2 ROM, they can use Skype android client. But so far, Samsung has not released their official 2.2 upgrade yet! If you want to upgrade Galaxy S with an official ROM only, then what can you do?

Well, I found an app which is very similar with the official Skype Client. It calls Nimbuzz。It supports IM,Skype-to-Skype calls, SkypeIn and SkypeOut. It only does not support sending SMS. So far their function is quite completed, but I tried it with 3G connections. The voice quality is not very good. Moreover, it used a lot of CPU and eats a lot of battery power too! Well, it can do the job, but that is not 100% prefect so far.

A few days, Skype released their "long waiting" Android Client. This is not a Lite Version,that is a full-version, which is similar with the one in iPhone and Windows Mobile.If you have a phone with Android 2.1 or above with 3G/wifi，you can use their IM and Skype to Skype call features。If you buy their skype Credit，you can send SMS to your friends around the world via Skype。Moverover，you can use the SkypeOut to make an international call. In additional, I believe you can use SkypeIn feature as well, even this feature is not stated in their official blog. This should not be a problem. SkypeIn is just redirecting calls from a landline number to your Skype account.

Wow!Skype for android is powerful!I bought Skype Unlimited Unlimited World subscription，therefore, I can make any international calls from skype anywhere.Too Bad Skype For Android doesn't support Galaxy S which is my phone！
