I'm currently on ios6 on an iphone 4s. I've held out on updating for quite a while because I don't really like changing things that work for me. However, I've reached the point where the apps that I use no longer support ios 6 and I need to upgrade. When syncing with iTunes I receive the option to update to 8 but I can't imagine that running well on the 4s. Is there a way to update to ios 7?
