Lost iPhone camera roll photos after iOS 5.0 upgrade
Question: I downloaded the iOS 5.0 software for my iPhone, and ended up loosing all my pictures on my camera roll. For some reason they didn't copy over after the upgrade and sync was finished. Did I miss a step somewhere?
Answer: Be sure you sync your iPhone before doing the iOS 5.0 upgrade, so that your camera roll photos will all be in iTunes. Then when you upgrade, they should still be on your phone or at least saved on your computer.
Photo sync settings in iTunes
Be sure you properly configure your photo syncing settings in iTunes, to make sure all of your photos are transferred to your computer when you sync your iphone!
To do this, connect your iPhone to your computer using your usb cable, select the phone in iTunes and then click the "Photos" tab.
Check the option to sync all photos (with iPhoto for the Mac in this case).
You can also transfer your camera roll photos using Window's built-in photo importer using the steps described here: http://www.rickysays.com/copy-iphone-pictures-to-windows
