I upgraded my iPhone to OS4 the other day (without drama, thank goodness). Yesterday I noticed a new icon at the top.
I thought, cool! It’s a compass pointing north! Then I realized that, from sitting at my desk at work, it was actually pointing southeast. That was my DUH moment. I realized it’s just the indicated that GPS is on. Then the other DUH moment. My 3G doesn’t have compass abilities.
Oh OS4, you did fool me there. But it’s ok, I’m smart again!
