The much-anticipated Skype app has been released for Android platforms today, and it may dissappoint some. Available for free download on the Android Marketplace, Skype’s app allows users to make calls to other Skype accounts, or to make calls over Wi-Fi and 3G depending on your geographic location.

Unfortunately for US users, Wi-Fi is the only wireless protocol supported, but 3G is allowed for international users and should come soon in the US. Skype will allow you to use your Skype credit when dialing traditional numbers, and it wont count towards your wireless plans airtime.

Samsung Galaxy S smartphone users are unable to use the Skype app at this time, login issues prevent users from using the software once it has been successfully installed. Also Android phones with resolutions below 480×320 will not be able to run the app. Video calling is not supported either, but you can always IM.

If you’re interested in giving Skype Mobile for Android a shot just head on over to the Marketplace from your Android device and search “Skype” to download. Let us know if it works for you as we’ve had no luck.
