I have a 3GS Iphone with the original version 3.1.3 system on it and firmware 05.12.01.   I would like to upgrade it.  I had to update to  itunes 11 and I am just getting the option of iso 6 when I select the update.  It takes forever for anything to happen so I have cancelled it.  Is there any tips or help someone could give me.  Thanks.

MacBook Pro, Mac OS X (10.6.8)
