Krullos:

Wrath101: Just bought a 3g version from Expert Infotech as I felt I don't need 4g.

After being told there is not difference other than the cpu, i felt comfortable.

However, the manuals are in arabic, the charging plug is wrong, and I have some Islam prayer app installed by default.

Pretty unimpressed.

Then I tried to install the free Navigon app available to NZ, only to be told it cannot be installed on my device.

Is there anyway I can hack this phone so everything about it is completely NZ, and I can install Navigon?

You could just install one of the official images from here: http://samsung-updates.com/device/?id=GT-I9500

...as long as you've bought the octa-core I9500
