One of the annoying things with iOS was that you could not do file uploads in web pages.
Thankfully iOS6 fixes this, at least in part, by allowing upload of images. This is excellent news. We can now use the web based image upload on photo sites.
Except! It appears that iOS6 strips all the useful exif data from the image - even the timestamp.
If, instead, you email the file, it contains loads of useful exif data including camera make and model (Apple, iPhone 5), aperture, focal length, exposure, etc. It even includes the location data in a GPS tag block.
So, nice new feature, totally bloody useless, thanks Apple!
