Hi. I have a really weird issue, so please bear with me as I explain it. Prior to updating to iOS4 I transferred purchases and backed everything up. The iOS4 update went without any issues. However, my 3G internet doesn't work. If I switch to WIFI the internet works, but no longer with 3G. I restored my phone on another iTunes and everything started working again. However, all of my contact, pictures, etc. were gone. So I then restored from my backup and everything came back, but the internet no longer worked again. Is it possible that my backup is corrupt? I thought the backup didn't effect the firmware? I just want my internet to work without losing my contacts, pictures, etc. Any ideas?
