As a commenter points out, Syphone doesn’t work with current or recent iPhone OS. Don’t waste your time.
Syphone is a Mac freeware application that allows you to archive your iPhone SMS messages to your Mac hard drive. Here’s a screenshot from my messages with Google Local:
If you’re using iPhone firmware 2.1+, you may get “No iPhones found!” in the drop down next to “iPhone” there near the top left. If so, go into Syphone’s Preferences and uncheck the box marked “Run helper app in the background.” Restart Syphone, and your iPhone and its messages should appear. You can change the colors, sort order, and export your messages to XML, PDF, or TXT.
Originally, I’d posted that I was unable to get the XML export to work. Ben commented that he was successful using XML export for one contact at a a time. This morning I tried again making sure I had one and only one contact selected. Success! Here’s a screen shot of the XML output:
Now I’m definitely tempted to study text messaging. Any workgroups out there who all use iPhones and want to be in a study of text messaging at work?
Syphone stores its database in /Users/<username>/Library/Application Support/MobileSync/Backup.
