I never said it updates through the firmware. I am just saying the Google Earth has updated its satellite images and my iPod Touch doesn't seem to be updating its satellite images correctly. I have played around with it for the last two days.
Update: Now my Touch is showing the updated satellite images on full zoom in. But when I zoom out a little the old satellite images appear. When I zoom out even more, the newer satellite images show. This is strange. What is even stranger is if I use the Hybrid map mode then I can't seen the new images when I zoom in.
