Having recently been welcomed into the fold of the iPhone collective, I have been overwhelmingly satisfied with the user experience.
That being said, I have hit a few walls while trying to figure out where some elusive features are tucked away. Apple had to enlighten me on how to get google maps to orient itself using the compass for example.
I was also left wondering how to enable Caps-lock on the iPhone keyboard. iPodObserver writes that the feature is strangely disabled by default but once enabled, double tapping the shift key toggles caps-lock.
To enable the feature, Tap Settings > Tap General > Tap Keyboard > Tap the Enable Caps Lock slider.
