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.
