Back in early 2005, Skype started the Alpha development for Windows Mobile and while the initial Skype client was only able to handle instant messaging, the later version added VoIP support. Now it seems that Skype has pulled the plug but it's not yet clear if this will be forever or if Skype is working on a new and updated Windows Phone version. Nevertheless, Windows Mobile users which are visiting the "Skype on you mobile" website will notice that Skype is now only showing the iPhone and Symbian as supported platforms while a footer notice explains that "Skype Lite and Skype for Windows Mobile are no longer available. For more information click here".
The Skype FAQ says the following:
Why can't I download Skype for Windows Mobile?
Unfortunately Skype for Windows Mobile is no longer available for download from our site.
We've chosen to withdraw Skype for Windows Mobile because we want to offer our new customers an improved mobile experience - much like the version that has proved so popular on the iPhone, and which is now available on Symbian phones. Our focus is on providing a rich user experience that allows you to enjoy free Skype-to-Skype and low cost calls as easily on the move as you do at your desktop.
We felt that Skype for Windows Mobile wasn't offering the best possible Skype experience.
Can I still use Skype for Windows Mobile if I already have it?
Yes. People who have already installed Skype for Windows Mobile can of course continue to use it.
Again, at this point it's not clear if Skype will release a new version for Windows Mobile which features the "improved mobile experience" as the iPhone and/or Symbian client do (at the end of the day it's up to Skype to improve the user experience of their own product) or if Skype for Windows Mobile is gone forever.
It's quite interesting that now - where first mobile operators have started to open their networks for VoIP use - Skype is removing the Windows Mobile client.
In any case, if you are a heavy VoIP user, there are free alternatives available anyway - most recommendable Fring, which is supported on all major mobile platforms - including Windows Mobile.
Alternatively, if you still have some money left in you Skype account, for now you can still download Skype for Windows Mobile through the link bellow.
