So before I started to download and installed iOS 5 I did a backup for my data. Then the whole installation problem started and I had to do a restore. After restoring I chose to do last backup to my iPhone so all my data could go back on. Then I noticed it said last backup was July 27, so everything I had on my phone after that date was deleted from my phone. So some of my photos and videos, contacts, and apps were deleted and all of my music is gone. I have no idea why it would do that since I backed up everything before I did this whole thing. Anybody know why this happened?
