putty,ssh等連接到iphone操作也可以
rm -rf /var/mobile/Media/Maps
mkdir /var/mobile/Media/Maps
mkdir /var/root/Media
rm -rf /var/root/Media/Maps
rm -rf /var/root/Library/Caches
rm -rf /var/root/Library/Preferences
ln -s /var/mobile/Media/Maps /var/root/Media/Maps
ln -s /var/mobile/Library/Preferences /var/root/Library/Preferences
ln -s /var/mobile/Library/Caches /var/root/Library/Caches
把地圖上傳到/var/mobile/Media/Maps/ 目錄下

，離線地圖開了也無效
有人看的懂嗎？
