I’m honestly not that much of a fan of the Android realm. But I understand a lot of people love their Droids and other Android-running mobiles. Skype knows this, as well, as they have just released their pervasive communication software for the Android Market.
Any phone running Android OS 2.1 or higher can now run Skype. Your Android device will be able to make Skype calls over wifi only, however, at least in the US. Of course, the standard Skype chat and address book synchronization will be available, as well. Samsung Galaxy S owners have reported some troubles with running the software but Skype’s reportedly looking into it. As on other Skype-capable platforms, the client will be free.
