Besides Microsoft’s recent announcement that Skype is being pulled off Windows Phone 7, All About Symbian also reports receiving an email saying basically the same about Skype for Symbian OS:
We’ve noticed that you are, or previously were, signed into Skype on a Symbian phone, and we’re sorry to inform you that we are now permanently retiring all Skype apps for Symbian phones. As a result, within the next few weeks, you’ll no longer be able to sign in and use Skype on any Symbian phone.
You can still stay in touch with friends and family using Skype on an Android device, Nokia Lumia phone or desktop computer. You can sign into them all using the same Skype account. The latest versions of Skype for all your devices are available at http://www.skype.com/download.
