Syphone

Syphone is a freeware Mac utility for use with the Apple's iPhone. The program installs on your Mac and does not alter the iPhone in any way. This application allows you to view, save, and back up your SMS messages. With Syphone you can now archive and view SMS conversations, including those that have been deleted from the iPhone.

Version 0.99b11:

• Connecting and disconnecting a phone without syncing with iTunes no longer causes a crash.
• iPhones with the same name but different serial numbers are now available in the UI and work as expected.
• Resizing the Syphone window no longer causes odd splash screen behavior.
• The helper application should no longer enter a CPU-intensive state when not syncing or otherwise doing work.

Requirements

Mac OS X 10.4 or later, iTunes 7.4 or later, iPhone.
