Trying to update to 4.0 and my back up is taking forever

Preparing for the 4.0 update i backed up my phone last night which took hours now that im trying to update the back up is still moving slow someone please help


Well decided that waiting wasn't worth it. Here's the solution:
Cancel the backup
Manually backup your iphone through itunes.
Then restore iphone. An option will come up that says "restore and update".
Iphone reboots after installation of os4. Then restore from backup in itunes.
That process took about 30 minutes and I was done.
