One of the most useful iPhone apps ever is free today only as a holiday gift from the developers. Ping! [iTunes download] works exactly like the iPhone’s native SMS app except your text messages are free. Ping! [Web site] basically uses your iPhone’s push notification system to simulate SMS msgs.
PROS
- You can send texts to iPod Touches (touché!) as well as iPhones.
- Integrates with your Address Book.
- Works with any iPhone/iPod touch, even internationally. For free.
- Did I mention you can download it for free today only?
CONS
- Works only with iPhones and iPod Touches. Any friends using other types of phones or devices are beyond your reach.
- You have to sign up with Ping for a user ID and exchange IDs with all your ping-able friends.
- Occasional jankiness with its stability; it crashes from time to time.
