I\u2019ve had a couple of hours to poke around in iOS 6, the iPhone OS update Apple released on Wednesday. It didn\u2019t take long at all to form some initial impressions. Here\u2019s what I love\u2014and don\u2019t love\u2014so far, based on my initial experiences using iOS 6 on my iPhone 4 and current-generation, Wi-Fi-only iPad.\n\tLet\u2019s start with the bad stuff.\n\tHate: No turn-by-turn directions on some iOS devices.\n\tFor a while now, Google has given Android users spoken turn-by-turn directions for free. With iOS 6, Apple gave Google Maps the boot and replaced it with its own free Maps app.\n\tBut turn-by-turn navigation is only available on the iPhone 4S, iPhone 5, iPad 2 or later and the fifth-generation iPod touch. Honestly, I don\u2019t see any logical reason why my iPhone 4 couldn\u2019t handle Apple\u2019s turn-by-turn navigation, especially since I\u2019ve been getting spoken directions on the device for a while now using Magellan RoadMate USA (a $50 iOS app). This is an obvious Apple ploy to motivate people to upgrade to a newer device, which, of course, I\u2019m planning to do anyway. And there you have it: a veritable microcosm of life in Apple\u2019s walled garden.\n\tMy current-gen Wi-Fi iPad won't give me spoken turn-by-turn directions either, not that I expected it to. You need an iPad with cellular wireless, as those tablets also have GPS technology built in and the Wi-Fi-only models do not. The footnote on Apple\u2019s Maps page, however, doesn\u2019t specify that turn-by-turn directions work only with cellular-enabled iPads and not iPads connected to a personal hotspot.\n\tHate: Siri is still \u2018beta\u2019\n\tThe guy that cuts my hair, Gene Hays, is just that: a guy. His name is not "Jean Hayes." And so, when I asked Siri to give me directions to Gene Hays\u2019 work address, she couldn\u2019t find "Jean Hayes" in my address book\u2014and Siri was, therefore, stumped.\n\tSo I tried a different route, asking Siri to \u201cgive me directions to Mes Amis 193 salon,\u201d which is the name of Gene\u2019s salon in San Francisco. Siri\u2019s response: \u201cI couldn\u2019t find any places matching "Meza me." On a second try, she couldn\u2019t find any places matching "Amazing me." On the third try, well, you get the idea. Siri is still sorry a bit too often. And she's not available on my iPhone 4, either.\n\tNow for some good stuff.\n\tLove: Bluetooth is now its own menu item in Settings.\n\tOnce buried under Settings > General, Bluetooth has come out into the light of day. It\u2019s now easily accessible in Settings, right under Wi-Fi, where it should have been all along. Hallelujah.\n\tLove: The new Privacy setting.\n\tSpeaking of settings, here\u2019s a new one: Privacy. App developers now have to ask your permission to access personal data on your iDevice. Using the new iOS 6 Privacy setting, in the general Settings list of items, you can see the information that's being accessed by certain apps. You can also easily turn that access on and off.\n\tLove: Reply With Message and Remind Me Later.\n\tWhen someone calls at an inopportune moment, iPhone users with iOS 6 now have four choices. Decline or accept the call, as always; decline and send a text message to the caller (messages are pre-written but you can customize them); or decline and set a time- or location-based reminder to call back. When you later receive the reminder, it gives you an option to click to call that person back, which is nice. These new decline-call options alone will save me time\u2014and perhaps prevent me from getting into trouble with my friends for not calling them back.
