Do you know which continents are in each hemisphere then?
I'm guessing Asia is in the north, so if you're in Jakarta would that still put you in the northern hemisphere, while when I was in Africa it had me in the south, so would that also apply to someone in Egypt?
If this is the case I'd guess:
North: North America, Asia, Europe.
South: Australia, Africa, South America, Antarctica.
Is this right?
