Does iPhoto show the EXIF information for a photo? Also, will it show the GPS location where a photo was taken? The built-in photo app will show the locaiton of all photos but to find the location of a specific photo takes some searching.
Don't know about the GPS data but iPhoto for iOS does show the rest of the exif data. Tap the thumbnail then tap the lower case i that is in the small square near the right side of the top bar. You'll get a small window with the data, original file size and exported file size.
