Skype working on Tango has come and gone with Microsoft and Skype announcing that the rushed-to-the-market Windows Phone app will not run on devices with less than 512MB of RAM. We then saw Nokia announce to the world that the Skype app will run on Tango Windows Phones (specifically the Lumia 610) with minimal amounts of memory. This was reaffirmed by Justin Angel using the app on his 610 to feature on a recent Windows Phone Central podcast.
Now Nokia HK has turned around and stated that they have decided to recommend to Lumia 610 customers that the Skype app really shouldn't be used and will not be available to those wielding the device. See the below quote from an email reportedly sent by the manufacturer:
"Nokia values the user experience provided by its products and services. Therefore, although the Skype Windows Phone version is workable on Nokia Lumia 610, after in-depth testing, we found that the user experience is not up to par with Nokia and Skype's expectation and decided not recommending users using Skype on Nokia Lumia 610. In the future, users of Nokia Lumia 610 would no longer be able to download Skype Windows Phone version from Window Phone Marketplace. However, Skype Windows Phone version would still be available for other users."
Looks like devices that are hitting the bare minimum requirements for Windows Phone Tango will not be able to run Skype. At least for now anyway. We're still looking at the Skype app as a pressed result from pressure mounting up on the teams to get something out on the Marketplace. We do expect the teams to sort out the issues and get the app working on low-end hardware as well as the flagship Windows Phones in the future. Our Rafael looked at why there are limitations with Skype on Windows Phone altogether, which is also worth a read.
