I was wondering when this was going to happen…

Hello, Gizmo5 is writing to let you know that we will no longer be providing service starting on April 3, 2011. A week from today, March 11, 2011, you will no longer be able to add credit to your account. Although the standalone Gizmo5 client will no longer be available, we have since launched the ability to call phones from within Gmail at even more affordable rates.

Thank you, The Gizmo5 Team
