Screen orientation lock

Thank you for your suggestion, and there is a tip for you:

if you don't like iPhone’s auto-rotation feature while using Galileo Offline Map, please use the screen orientation lock option (requires 4.0+):
* tap the HOME button twice to bring the multitasking dock,
* swipe your finger to the right until you see the music control buttons,
* tap on the lock button (first in a raw).

After you enable the screen lock, the auto rotation is disabled and your screen is locked to the portrait orientation. A rotation lock icon (looks like a circular arrow around a padlock) will appear in the status bar next to the battery charge icon.

To re-enable the auto rotation, you can simply go through the steps again to turn off the lock.
