So far, so good on my end. The Mrs. and I both have iPhone 4S and have upgraded. I’m not seeing any issues, and frankly, it doesn’t act or feel much differently at all. Maps is the biggest change, of course, and it still gets me where I’m going, and I do like the turn-by-turn navigation that was added. I haven’t run across any of the glaring bugs that other people have reported with Maps.
I do like VIP notifications, but I haven’t played around with the settings much yet, or the do not disturb feature. I need to do that soon, as I’ll be on travel.
I also upgraded the eldest child’s hand-me-down iPhone 3GS (cell service deactivated — basically being used as a somewhat bulkier iPod Touch 3rd gen, plus camera and microphone) and don’t see any problems there, either.
A month ago, Google maps sent me and my girlfriend on a wild goose chase that put us on a dirt road that Google maps indicated was a paved road. A pothole I hit that I could not see because of the angle of the sun just at dusk on that road cost me over $500 in damage to my car and tires, not to mention recking havoc on my and my girlfriend's backs. On turning around we saw potholes we had luckily missed that my girlfriend says would have swallowed a Volkswagon! Testing Apple Maps on the same route search, the it found did not take us on that road, but found a SHORTER, safer route to our destination. . . on PAVED roads.
Now, it turns out that Motorola (owned by Google) has taken to publishing advertisements that use NON-EXISTENT addresses to show Apple Maps not finding them in Maps... while Google Maps finds the non-existent locations. Strange. However, it turns out that Apple Maps DOES find it... because what they showed, was that Apple found the RENAMED street and location! LOL!
In other instances, Google Maps showed illegal turns that if followed would get the driver a $250 ticket, while Apple Maps showed the correct LEGAL route... in downtown San Francisco... in Google's backyard. Google's Street View even shows two prominent No Right Turn signs at that intersection, yet their mapping says to turn right to get to the freeway there, instead of the correct route one block farther on.
