Scott I did not know about the local maps option for iPhone or Android, but thanks for the update.

As for BBMaps, I found it incredibly useful during a recent trip to Europe for a month. I used it extensively in every city I visited. I would load up the maps via wifi in the hostel (you must pan over the city areas that you will visit at a zoom level 2-3 steps from the closest to get all of the data loaded) and then using wifi search for locations either via address or local search and save them as waypoints then layer them in place. On the street, you cannot get turn by turn directions, but you can "Find a Location", select one of the points, and it will show you an arrow and an as-the-crow flies direction to the point. I also found it very useful to pre-name each of my waypoints by the city so that I could search for them easier (yes I could have sorted them in folders but even still typing is faster than browsing IMO). Finally, like I said you don't need to enable unlimited caching, but to insure that you don't loose any maps that you want I did. I currently have about 5MB worth of maps stored and that covers more than 10 major cities, decent level overviews of most of Europe for train rides, and some places back home.

If you have any questions on it, please let me know. I can't suggest it enough, except I wish I had a blog myself with a big enough of a following to lay it out there for the public lol, but better someone does it.
