I have an Iphone4. I made the mistake of attempting to sync it without realizing that I had inadvertently selected my wife's Iphone3 mode. Seemingly, all of the features/apps, pictures, contact information, info on notepads added since July 1, 2011, have been removed. Primarily, I would very much like to know what to do to restore the original settings of the Iphone4. Thanks.
IF you have a backup of your phone - make sure you do. Then do this on your phone - settings - general - reset - erase all contents and settings. This will wipe your phone clean of all data, then go thru the prompts.
