Just noticed that 1Password, a great wallet application created by Agile Web Solutions that I've been using on my Mac for quite a while, has hit the iPhone App Store. The iPhone application, which can be downloaded free of charge allows to do a wireless sync with Logins and Secure Notes maintained on the Mac. Great application and works like a charm!

Make sure to use the latest version (Beta 1 as of this writing) if you're on a PowerPC. Otherwise syncing will fail with a NSInvalidArgumentException exception!
