The first version of Skype for Windows Phone will not support low-end "Tango" devices, Microsoft has revealed. Although the company delivered a 1.0 release of Skype for Windows Phone over the weekend, Microsoft says it will only install and run on devices with 512MB of memory. The majority of Windows Phone devices include 512MB of RAM, but Microsoft's latest "Tango" handsets only feature 256MB of memory.

Described as a "known issue," it appears that Microsoft's Skype team may be planning to support Tango devices, like the ZTE Tania or Nokia Lumia 610, in a future release of the software. The company also lists a number of other known issues, including an app foreground limitation for receiving communications and the lack of SMS send support. We've reached out to Microsoft find out whether it plans to support Tango devices in future, and we'll update you accordingly.
