How long does iPhone 4 4.1 update take?

I've tried this three times now and it just seems to keep getting stuck...the phone shows the Apple logo and a progress bar that's a little more than halfway through. iTunes has a box that says "Restoring iPhone Software" and the progress bar is a few millimeters from the end. And nothing is happening.

I downloaded the update file myself, so I thought maybe that was corrupted, but the MD5 seems to match up with one I found here: http://forums.macrumors.com/showpost.php?p=10986822&postcount=595

MD5: ac3031a7b5c013d6a09952b691985878

Is this supposed to take 1+ hours? What could be wrong?

I'm still using iTunes 9...would v10 help? That shouldn't break any jailbreaking, right?

 

Looks like it was the host file problem...hadn't commented out the gs.apple.* line. Fixed!

 

Go to /private/etc and open the file called hosts. you'll see a bunch of IP addresses followed by host names. put a # in front of any line that has gs.apple.com. Save, authenticate, and try the update again.
