Both me and my dad have iPhone 4s and we both have the same irritating problem. When we switch OFF automatic network selection, it can take literally 5 - 10 minutes for the iPhone to list the available networks below. Because we live on the border between Ireland/N.Ireland, we cannot keep our phones on Automatic as it means we end up roaming networks. I have just restarted my phone (holding in both buttons), turned off Automatic and searched for new networks and it found a list of available networks within about 15 seconds? Has anyone else had this problem?
