I received an email today from Android Market:
This is a notification that the application, Google Voice Callback FREE, with package ID com.xinlu.gvdial has been removed from Android Market due to a violation of the Developer Content Policy. For specific details regarding this particular suspension, please see the Intellectual Property and Impersonation or Deceptive Behavior sections of our Content Policy. Please also be advised that aspects of your application’s listing in Market, including but not limited to the title, logo, description, and posted screenshots are also subject to the above terms.
So, while I wait for response from the Android Market Team, Google Voice Callback will be (hopefully temporarily) unavailable on the Android Market.
[Since I'm completely inept on the artistic side, I smash the Google Voice icon with a check mark to make an icon for the app, which, in hindsight, is probably the cause of suspension. Finger crossed that Google will let me publish a new version after changing the icon...]
Update: the app is still available on Amazon Appstore. If you bought the donate version on Android Market and do not want to purchase the donate version again, please send me an email.
