I think I spoke to you on hofo, the app you are looking for is public transport beta, if you need the link I have it, second you should always be on generic firmware, not on some carrier or region branded firmware... Thedead1440 will probably come in and explain better when he's here... Edit: here is nokia public transport https://www.dropbox.com/s/o1av1txk50....0.3_armel.deb Transfer it to your emmc and double click on it, it should install.
