Trying to search for the nearest branch of a cafe last night on a Apple iPhone 4, updated to iOS 6 is that the Maps application is virtually useless in the Philippines. I have read complaints from users abroad saying that it takes them to the wrong place. No similar problems in the Philippines. It won't know the place exists in the first place.
Google Maps finds every branch in the country, and even some obscure places with the same name I did not know existed.
The problem would be a poor database. For places in the database, trial and error will be needed to find out if they are in the correct place. Another issue, could be typographical errors so the Map will not identify the place you are looking for. A friend of mine on her iPad 3 tweeted "check out UPD map. Kalayaan residence hall typed as 'Kalayaan Schoolicidence' haha!." A simple spell check should have detected that.
Over time that will probably be corrected. But this habit of Apple launching beta software is getting tiring. Last year, it launched Siri, as a beta, but from Apple advertisements you would not think it was beta software. But, it was not a big deal. It was an additional feature which you could simply ignore.
Mapping and locations software is one of the key features what makes a smartphone a smartphone. Apple's iOS5 had a very good map and locations software, in Google Maps and Places. iOS6, well it uses Apple Maps, which should not even be called Apple Maps Beta. It should be considered an Alpha release.
So while Apple wows us with supposedly better 3D views and features, basically, iOS6 throws all the nice hardware in the iPhone 5 back to the stone age.
Apple, please fix Maps. In the meantime, give users back Google Maps.
