Client Ifbyphone has been accepted into the Apple iPhone Application Store. They along with Truphone puts two Comunicano agency clients in the program there. Friendly company and sometimes client, MyNuMo, also has one there.
IfByPhone's first application allows users to select multiple contacts on your iPhone and quickly and easily send a voice broadcast to them instantly or at a future scheduled time. What's great about this is it doesn't chew up minutes and works over the WiFi, EDGE or 3G connection.
If you want to check it out, go to the Apple Application store.
