If you have an iPhone or an iPod touch, we’re offering a refund of the $4.99 purchase price of Conference Starter, the app that lets you start ad-hoc voice conferences. You can create a conference with anyone who has a phone number and there are no PINs or call-in numbers to remember.

Here’s how it works. Conference Starter lets you pick up to 25 contacts from your address book (or type in arbitrary phone numbers) and touch “Start Conference”. The system then calls you and asks if you would like to start the conference. If so, everyone else is called and asked if they would like to join. Eventually everyone is dropped into the conference together and everyone can talk. Each participant deducts $0.02 per minute from your credit while in a conference and the conference ends when you hang up. (or you run out of credit!) When you buy the application, the $4.99 purchase price is added to your account as credit.

If you would like to give it a try for free, we will refund the $4.99 purchase price of the app to the first 50 people to sign up here:

Don’t worry, we’ll confirm that you are within the first 50 before you have to go buy anything!
