On the bottom you can find the following disclaimers:
* Skype is not available in the Android Market in China or Japan.
* Skype has been tested on HTC and Motorola devices with Android OS 2.1 and above. It may work on other Android phones, but we can’t guarantee full functionality or compatibility.
* We’re aware of some problems with the Samsung Galaxy S, and we’re looking to address these in the future.
* It’s free to use Skype in a WiFi zone. If you use Skype with a mobile data connection, operator charges may apply, so we recommend an unlimited data plan.
