iOS 4.3.1 iPhone 4 some settings reset
Since then I've noticed some of the settings have reset to the default.
The Ringtone and Text tone have reset to Marimba and Tri-tone respectively and the 'Show Preview' message setting had reverted to On.
Phone is not jail broken, the other settings remain how I had set them.
Has anyone else seen this behaviour?
