Thank you for the answer.
If it is Symbian phone, Will it run .sis and .sisx files? Also, Is that all? Different is "Chrome front" thing, no color sidebar of the side of phone and contents of it is different. Nothing changed inside the phone? I mean better stuff, faster, stronger or better with the GPS? I want to know more information about the difference and which is better in your opinion?
Since it is a Symbian phone, it will run .sis and .sisx files. The performance is pretty much the same, RAM, Memory etc. If you want the phone for Navigation, get the navigation edition because it will come with the things needed.
And it didn't list the differences in the box contents, let me relist them sorry:
