For those of you who have got your very own iPhone 3G - and those just dreaming of getting your mitts on one - I choose 10 of my favourite tips to help improve your iPhone productivity.
If
  you’ve been one of the few fortunate enough to get hold of an iPhone 
3G  you’ll know not only about its style factor, but also all about its 
 highly intuitive interface and ease of use.
However,
 precisely  because it’s so easy to use, very few people are ever going 
to look at  the manual, which means that they’ll be missing out on a few
 tips and  tricks to help them get the most from the device. 
And,
 for many  people it’ll be the first time they’ve used an iPhone. So to 
help get  you started, we've put together a quick list of ten items to 
help you  get the most from the much vaunted device. 
1. Caps Lock feature
If  you’ve ever tried to type in all 
caps on the iPhone you’ll know that it  doesn’t appear to have a Caps 
Lock function, which can be quite  frustrating when you want to really 
SHOUT in an email. 
Actually  there is a
 Caps Lock feature, it’s just that you need to activate it  manually by 
going to Settings>General>Keyboard (scroll down). Once  enabled, 
you activate it by double tapping on the Caps button, which  then turns 
blue. The only question then, is why the feature is off by  default...
This  is a tip that is actually 
written in the Keyboard settings page  described above, but unless 
you’ve been to that page you won’t have  spotted it. A real time saver 
when you’re composing emails.
As  you type, you may have noticed 
words appearing underneath your chosen  letters. These are suggestions, 
and you may be wondering how to select  them – simply hit the spacebar. 
Cleverly, it also creates a space for  you. Even more clever, though, is
 that if you choose a selection and  then double tap the space bar to 
put in a full stop (see above), it will  take out the space it’s just 
created. It’s like it’s thinking...
If  you’re the sort of person that 
likes to write words precisely as they  should be, even when typing a 
text message, (as in, a pedant) then  you’ll be pleased to find out that
 you can easily type accented  characters on the iPhone – just hold down
 the keys (E, Y, U, I, O, A, S,  L, Z, C, N) and the list of alternative
 pop up. Hold and down and slide  across to choose the one you want. 
Touch.
It’s  possibly a bit niche this one, 
not to say geeky, but with the 2.0  software you can now take 
screenshots on your iPhone. You simply hold  down the Home button - 
that’s the actual physical button at the bottom -  and then press the 
power button at the top. The display will flash and  the image will 
appear in the camera roll. 
The  problem with having no physical 
buttons means that it’s harder to make  shortcuts. However, if you 
double press the home button, it will take  you straight into your list 
of favourite contacts, enabling you to make  calls quickly. And, if you 
double press the home button when the display  is off it will bring up 
Play/Skip buttons so you can get to your music  without even having to 
unlock the phone – perfect for listening to the  IT PRO podcast.
In  the iPod application there are a 
number of options at the bottom – the  iPod bar. However, you can 
customise these to your liking – simply  select More, then choose Edit 
at the top left and select the icons you  want, and drag them down to 
the bottom. 
If  you want to remove an application 
from the iPhone - or just move an  icon to a different location round 
the screen - you simply put your  finger on any icon and hold it down, 
and after a few seconds every icon  will start to shake with an ‘x’ 
appearing at the top left. You press the  ‘x’ to remove it, or you press
 and drag the icons to your preferred  locations on the screen, or even 
over to the next page of icons. Worth  trying just to see the very cool 
shaking icon effect.
If  you’ve got a web page that you 
like to visit regularly, then you can  place an icon directly on the 
home screen so you can get straight to it.  Press the ‘+’ symbol at the 
base of the Safari web browser and choose  Add to Home Screen.
This  is actually a well-known 
keyboard feature, but just in case you don't  know it, you should. If 
you make a mistake while typing, hold down your  finger over the word in
 question and then a magnifying glass will appear  enlarging the text. 
By rolling your finger gently, you can place the  cursor precisely, 
enabling you to correct erroneous letters.
