Whistle brings free contiguous US calling to your iPhone or iPad over WiFi or 3G. Whistle works out of the box with the 4th Gen iPod Touch. For previous generations, you'll need headphones and a microphone.
Whistle provides free ad-supported 20 minute inbound and outbound calls to and from your Whistle number. Whistle notifies you of calls through Push notifications.
You can also make unlimited length, ad-free calls to continental US phone numbers for a low, per-minute rate.
FOR A LIMITED TIME, we're giving everyone the opportunity to use as many pushes as they want. After this initial offer, push with limits will be free and unlimited push will be available on a subscription basis.
