As we all know, the iPhone has a limit on the number of SMS messages it can store at one time, and if this limit is exceeded, existing conversations must be deleted in order to make room for new messages. To remedy this potential inconvenience, Micromat has released Syphone, a free utility that provides SMS text message archiving from your iPhone onto your Mac. This application lets you view, save, and back up your SMS messages and installs on your Mac without altering the iPhone in any way.

The program allows you to view and/or save any conversation, including deleted messages. It uses the familiar iChat format to display archived SMS messages. Additionally, if you have multiple iPhones synced to your computer, Syphone allows you to view and archive messages from any of the iPhones.

Syphone is presently in beta and is a free download from Micromat.
