Feel free to vent your opinion in the following thread located in the Cloud Ideas section where others are voicing their displeasure at WD dropping support for Windows phone.

Edit to add: But as mentioned before in these threads because the Windows Phone occupies such a small market share (less than 4%) of the mobile phone market, WD apparently (until they publicly state otherwise) feels its not worth the time, effort and money to update the Windows Phone app to work with the OS 3 firmware/MyCloud.com portal.
