Photos missing after updating to ios 5.5.1
When the IOS 5.1.1 update became available a few days ago, I decided to update. Before doing that, I attached my iPhone 4 to iTunes and synced the phone. When that was complete, I initiated the update.
Once the update was complete, I noticed that all of the photos and videos I had created since mid-March were missing. Are they stored on my computer from when I sync, and if so, how do I access them? Otherwise, why did this happen and how do I prevent it in the future?
