Hi everyone,
I have already downloaded and installed iOS 5 and updated my iPhone 4 with it. But no matter how many ways I try to get my pre-purchased apps back on my phone(photos, contacts, emails, messages etc. are still on my phone), they won't go back on. I've backed up, restored to backup, synced, transferred, etc. and it still won't work. Please help! I am not very techy

I also tried to perform a backup using iCloud on my iPhone but that's not really working either...

Feedback anyone?
