Which iPhone is it? If it is a 4 try tapping the bottom button twice you should get the icons in a moveable row along the bottom of the screen. As the experts say ....... Have you tried switching it off and on?

It's refusing to do anything and it's an Iphone 4s I hate it   the only thing it needs is a hammer smashed into it right in the middle 

 

I shall try - thanks GJ 

I've just read again and obviously my info won't help. Have you tied connecting it to the parent computer? Don't know if that would help. Last time I had an issue I took it into the local O2 shop and they fixed it in seconds and told me what to do in the future.

Or you could ask online?

tapping the button twice brings up settings but the screen is still to big to read what my options are and it is stuck to the right hand side.  No amount of pinching to make it smaller works and it refuses to move to the left hand side so I can read it 

asking online is where I got the information about what I mentioned above.  I guess I'll have to go into the shop.  Thanks anyway 

apparently triple tapping with three fingers works (from google)

 

Edit: I mean the screen not the button

When I say ask online, I mean on the O2 site. You can often get one to one with an advisor. In my experience they are very good.

 that's not working either 

I'm with 3 so I might try them

Here they say you've put it into  accessibility mode and that Zoom can be turned off in universal access when connected to iTunes.

 

Jen you were right about the double tap with three fingers - I've just done it   of course it would have helped had I used 3 not 2 fingers 

 

I still hate this phone with a passion  only another 21 months left on my contract  which means 21 months of threads like this  

 

I should set up an Iphone help thread so I can permanently sit there with my problems 

Pengy make sure you go turn it off, go to settings> accessibility>zoom>off so it doesnt happen again

have done - you know what I'm like with this phone 

Ah it's a learning curve Pengy, i bet by the time your contract is up you'll love it

no chance 

I much prefer my old 3 which is now being misused by Mrs Jer.

sometimes I think these new fangled improved smart phones are just too smart for their own good - you need an 'ology in iphone speak before you can use them 

Mine is a 3gs and i love it, although I'd like to have a flash and be able to use flash light app but i don't think that's worth the cost to upgrade!

*puts hammer back in tool box* 

I'm useless tech wise.  The apple store is only 10 minutes away so I just pop in there when I get stuck.

It took me longer than 10 minutes just to find out how to park in there. Things you only do once part 94. Visit the metro centre. The apple store staff were brilliant though but.
