Another blow to carriers (first one was when Google Voice App got approved by iTunes), Skype for Android is now available that works on all phones (not exclusive to Verizon only). There are few limitations though, first of all you need Android 2.1 or above on your phone and secondly; the for US citizens the App is WiFi only. That means you cannot make free calls (oh No!) via skype using carrier’s network, you have to have a WiFi connection. However, that limitation is for US only, you can use the App to make calls using network if your live outside US (3G network required).

This is a big moment and obviously we don’t expect this to be a perfect release. Some road blocks; Skype is not available in the Android Market in China or Japan, it’s buggy on Samsung Galaxy S phones, moreover operators may charge you for using skype over their network (outside US). There are two ways to download the app, either by visiting skype.com/m on your phone or via Android market. Make sure (Settings > About) you have Android 2.1 or above on your device. The application has 9MB of download size and takes 14 MB space for installation in your phone. [Source]
