I couldn't disagree more. Maps have seen very little updates where I live since the initial launch. And I have not gotten a single response from a map correction report nor has a single issue I have sent to Apple been fixed. There are a huge number of threads on this forum about this very thing. If anything Apple has a terrible system setup to make corrections (mostly because they don't own the data).
I agree with this. Probably it's because I'm in the UK rather than the US where they seem to be concentrating all their effort (don't know about you) but, hey, maps are global by nature, as is the iPhone. They need to sort this out.
