Ok, so here is what I am thinking: Follow the instructions here, but instead of doing it for the iPhone software, do it for the iPod software. Then extract the maps app from the ipod software, since this app will be configured to JUST look for wifi signals. and then copy this onto your JB 1.1.3 and it should work! problem is, i have a mac....... so i cant do it, but can someone else try this???????
