Despite the statement on the official blog of Skype and Skype spokesman for the declaration of the views in this article, Nokia has contacted Engadget to alert them that the application in question "after some difficulties early on," works well on your Nokia device Lumia 610 (which include using a RAM of 256 MB).
“Skype is available for the Lumia 610 in Marketplace and actually works just fine in the latest round of testing that has been done.”
