Telmap Navigator - works even on my old 8310 and gives excellent worldwide turn-by-turn 3D, 2D or symbol guidance, with voice. All the features I need from a Sat-Nav, I've used it here in the UK and on holiday in Oregon extensively. Unlike the iphone I can still multi-task when it's running too! (handy for checking / writing mail without losing a route if you stop on the way).
I don't know why I'd ever move from my 8310 - it does everything I need it to do (camera, video, Opera web, corporate email / calendar, sat-nav, alarm clock, mp3 player) even though it's a couple of generations old now. Maybe I'll grab a cheap Bold when this one finally breaks - though if they add phone to the PSP as was rumoured a couple of weeks ago... 😀
