What this does:
Allows the creation (on a PC) and loading (on an iPhone) of a custom MapTiles cache for Maps.app on jailbroken iPhones (tested on 1.1.2)
note: Maps.app map layer only zooms in down to 1 so click Advanced and set min zoom to 1 in GMDL, or put the map in the satellite layer which goes to -3.
note: probably does not work on 1.1.3+ due to a different path (you can probably modify and use the sh script instead from http://www.in7ane.com/iphone/lm.sh by changing root to mobile)
Hey bro, I remember using your app for the PSP, so AWESOME!!!!! I've already got the whole of London, I will use that and try it out. Will have to see though, running 1.1.3.
Directions do work, but you do need a network connection (Maps.app queries Google's servers to get directions). The other thing to note is that if a directions/location query makes Maps.app jump outside of the area covered by cached tiles it seems to forget about the cache and start downloading tiles again.
