This had the smell of inevitability about it. Yes, a Russian hacker got 3D maps working on an iPhone 4. It's not complete and turn-by-turn directions aren't working yet, but it's a start.
SlashGear has the story via Russian site iguides. There are instructions on the web, but they are not for the faint-of-heart and require the just released iOS6 jailbreak.
I expect there are a lot of disappointed iPhone 4 users out there who are pretty upset that the maps app has so little functionality on their older phones. I could make a half-case for leaving the 3D flyovers off
