Hi all. I have a problem with my 3G.
It's running 3.1.3, and I went to upgrade to 4.1 last night. After over an hour, the iPhone screen was still showing only 2/3rds complete at the restore step. Would not go any further. I had this exact same problem when I tried going to 4.0. I ended up having to go round to my sisters and do the process through her PC, and it worked fine. All done within 15/20 mins.
I'm running a Macbook with all the latest updates for software and OS, iTunes 10. Phone was synced before starting the upgrade process. I can't even downgrade the phone as it's stuck in recovery mode now, and however I try to things, like going back down to 3.1.3, it just gets stuck at the same point in the recovery process.
iTunes Version: 10.0 (67)
iPhone OS before update: 3.1.3
OS Version: 10.6.4
