I've already downloaded close to 150MB of the Greater Toronto Area - in fact a nice square of the Golden Horseshoe, which includes the area of land along the shores of the North West of Lake Ontario. The detail doesn't go down to residential street level. Aren't these maps supposed to be made up of vector plots?

To get good detail of the GTA, it would either take long enough to get frustrated by the program until such time as I made a $1000 offense (smashing the iPhone). Or three months of patient scrolling, marking and downloading.

Oh, and you can't search for any street names no matter what level of detail you've downloaded or if you're on/offline. It only searched its pay guides. And I don't think it searches those for street names either.

I'd like to revise what I said earlier. Not useless, but... NEXT to useless. Absolutely shite UI and poorly designed functionality.

By far the best app I've ever downloaded is Service Bell. It does exactly what it says it does and does it very well. It shows an image of a desk bell and you can tap it to ring it. That's it.
