This seems pretty good from a first glance; provides a "Standard" or "Classic" option to select between Apple's and Google's Maps. If you just care about tiles (rather than e.g. transit directions) then this should be a good stop-gap until Google releases their own version. It's a nicer experience than the mobile Google Maps site.
The web version of Google maps is already more powerful. No directions, layers, no streetview, no auto-matching, no reviews etc. Loads slower. How is this nicer than the web version by google (other than the obvious, ie lack of a URL field)
If you haven't in a while, look at the latest google web version they've made some changes, e.g. look up Brooklyn Bridge, NY.
It's in the Apple App Store ( http://itunes.apple.com/app/classicmap/id566173771?mt=8 ). I presume that means Apple have looked at it, and approved it, and it won't be yanked in a while for breaking any terms of service,
1) Because there's very little evidence that malicious applications are successfully filtered (many get in), and much evidence that nitpicky comments keep 'good' applications waiting.
Don't know about no 1 but Google's TOS explicitly forbids the rendering of Google tiles outside a Google application, you can only use them in conjunction with Google's own Maps API.
It doesn't credit Google as far as I can tell (the legal section just seems to be for the new iOS maps). The link to "Legal" is really small and there's no Google Logo (as Google had required previously)
Still it works if you all you need is map tiles (which I highly doubt what most people use Maps for)
