Skype is available for Pocket PC in a new version 1.2, which for the moment is still in beta status.

Skype for Pocket PC provides you with the freedom to enjoy Skype on the go: in the home, office or outdoors - wherever there is a high speed data network (WiFi, 3G or EDGE) which your Pocket PC can connect to. So, find your favorite WiFi hot spot and Skype away. If you get an EDGE or 3G enabled Pocket PC with a high speed data plan, you can really start going places, while talking to your buddies for free.

Version 1.2 offers the ability to make Skype to Skype calls, Skype Out calls, instant message chats and to send and receive voicemail. We also worked hard to provide good voice quality. Supported languages now include: English, German, French, Traditional Chinese, Simplified Chinese, Italian and Spanish.

For the best sound quality Skype Team recommends to use earphones, a device with a CPU of at least 300MHz as well as built-in WiFi. If you don't plan to use earphones, we recommend you turn on the 'echo cancellation' in the Skype application (You can do that under Tools / Options in the Skype PPC application). If you plan to use an external WiFi card, your devices should have at least a 400MHz CPU.
