problem: the youtube app that had been packaged with iOS disappears upon upgrading to iOS6
solution: go to the app store and download the new youtube app

problem: apple maps replaces google maps
solution: use google maps via safari (personally, i have been using apple maps and have not gotten lost, but others have found issues. i never use satellite view, so the distorted satellite pics do not affect me. my lack of annoyance with apple maps does not change the fact that apple has some work to do...)
i upgraded my iPhone 4 and have had no problems. my battery life has been steadily deteriorating for the last 3 or 4 months so i can't tell if the upgrade has affected battery life. i'll be getting an iPhone 5 in a couple of months when my contract is up, so i'll deal with this annoyance until then.
