Criticisms aside, the iPhone display is remarkable for its multitouch technology, which allows you to move your finger in a variety of ways to manipulate what's on the screen. When in a message, you can magnify the text by pressing and holding over a selected area. And as long as you don't lift your finger, you can move your "magnifying glass" around the text.
You can zoom in by pinching your fingers apart; to zoom out you just do the opposite.
I'm reading about the Iphone and it appears the same applies to pictures...
stuff im reading:
"Picture pinching or using two fingers to zoom on any content is certainly fun"
It may be worth mentioning that iPhone allows you to zoom in ("pinch out")
I dunno crap about the iphone tho so maybe that stuff is referring to other things.
it's too expensive is all I know.
