My iPhone 4 is version 4.3.3 and I already updated my iTunes to 10.5. However, I cannot update or restore it!! Help?

It keeps saying that the device is not eligible for the requested build!

If you've ever used TinyUmbrella, open it, uncheck "Set Hosts to Cydia on Exit".

Or go to edit /etc/hosts and remove the apple lines.

Thank you for everything!
I was really worried just now ><
For some reason my iTunes just refuses to restore/update no matter what I do. I tried putting my phone into recovery mode - for those out there whose mac is unable to restore/update your device, chances are it can't restore your device in recovery mode as well! Best shot would be to use a windows laptop/pc, download iOS 5 then connect back to your mac (remember to backup on your mac first! when you click update on your mac they will backup your phone first, even if you can't update to iOS 5 on your mac.) then ta-da
