Tips to make your iPhone 4S experience more efficient

There's no need to kill any app at all.

That's just a recently used apps list, once you press "Home" the app hibernates saving its state at that moment, so when you pick it back up, it will look like it has run in the background.
"Killing" it just wipes its status, so when you'll open it, it will appear like fresh new.

iOS multitasking is like MS-DOS 5.00 loading a CD-ROM driver.

Quite surprising that such a well known misconception has been blogged by such an authoritative source.

Create folders, kill apps, fool around with options? Aren't these a bit basic? Weren't these "Tips" provided upon release of the upgrade and then about a million times thereafter? I assume I must know the phone pretty well since I haven't read about anything beyond what I already knew since about a week after I got the phone. Find something a bit deeper than, "You can add a new page by downloading more apps than fit on your current pages."

Here's one that I think is helpful and not that obvious or over explained. You can add Shortcuts by going into General Settings then to Keyboard and add any shortcuts, such as ttyl which will then turn into "Talk to you later." after typing ttyl space. You can create whatever you want.

But you probably already knew this

Can somebody tell me how to Bold, Italicizes or Underline text typing on an ipad or iphone? Is it possible? The "BB Codes" above imply that it is possible, but highlighting text and then typing "/b" simply replaced the highlighted text with "/b". Help.

Instead of typing an email, tap the microphone icon on the keyboard and start talking. your words will appear as text. Use dictation to write messages, take notes, and more. Dictation also works with third-party apps....
