Best list of iOS 5 tips and tricks and hidden features comes from Chris Herbert at MacStories.
Because the iPad has a much larger screen, Apple has included more gesture options for it. Apple added a few moves and shortcuts: using four or five fingers, swipe up to reveal the multitasking bar, pinch to return to the Home screen and swipe left or right to switch between apps.
Similar, though fewer fingers are required, exist when editing text on the iPhone.
iOS 5 sets the alert to the new Banner style that shows up at the top of the screen. While this is minimal and not intrusive, I like some alerts to be displayed the traditional way. To change any of your app’s notifications, go to Settings.app > Notifications and select the app you want to edit.
In other words, you control how the notifications are displayed on the home screen of your iPhone and iPad. Choose wisely.
No more do you need to slide to unlock, then locate your Camera.app and launch it. Now, with iOS 5, you can double-tap the home button when the device is locked and a new camera button will appear next to a shortened slide to unlock bar. Tap the camera button and you’re shooting!
This is long overdue, but done right. If you can remember what to press. Also long overdue are custom alerts for all the new notifications.
Apple has finally added the ability to use custom tones for texts, new voicemails, new e-mail, sent email, sent tweets, calendar alerts, and reminder alerts – just about any alert style.
Overall, no issues have popped up with iOS 5, and there’s plenty new to like.
