My iPhone 4S (that is only a few months old) is struggling with iOS 6. It keeps losing my bookmarks and then magically 12 hours later they're back. It stalls coming out of apps a lot of times. I have the mysterious wifi issues. Honestly it's a lot of little things that are just starting to dislike iOS and I don't really want switch operating systems because I don't like the other ones. I rarely complain about iOS but the last few weeks I find myself getting frustrated with my phone more and more. I have an upgrade available but was going to wait a few months and wasn't in a hurry but wondering if it seems that ios6 is better on the 5 and this will reduce my headaches.
