iphone does almost exactly the same nokia would do..

using xgps on jailbr... iphone u can have the direction you are going, no needed for internet, just your GPS..
nokia 5800 doesnt make any routes without internet, or does it?

iphone also doesnt do that function, but having internet on iphone you can make the route on it, with the maps app...
with the help of offlinemaps for not using too much kb's .. if you only open maps with the appropiate offline map loaded on it, the only information u're iphone will get is the route.. few kb's..

okok i got out of the topic..

but this also answers some questions of other users
