I dont have an adroid phone yet but well to my knowledge to copy something you highlight it then hold on it, eventually a menu appears with copy option.

Same goes with images im sure.

 

Yeah it's missing from most things, slightly annoying.

 

You can certainly copy and paste from web pages, by bringing up menu then going to "more" or whatever it is, and then a load more options appear including select text. It's the same menu (or close) to that which appeared on my HTC Hero when long-pressing on a web page, for some reason there's no long-press menu on the Nexus One, instead you have to go through the menu button.

As for emails, no, there's no way to copy text from emails which is really annoying when someone sends you a telephone number in a way that the phone doesn't recognise (e.g. if it's got brackets around it!), with multitasking you'd think you could flip between the contacts/phone app and the email app and tap the number in, but when you switch away from contacts/phone it dumps what you've done already and resets so you need to put the details into another note app and copy/paste from there (e.g. Note Everything).

 

Oh, I did not know you could copy from a web page like that, awesome!

 

Once you've chosen select text, you can then either swipe some text with your finger or use the trackball to move a cursor, however I've found it a bit troublesome if you want to select text that goes off the bottom of the screen. I've not tried zooming out yet.

 

oh, come on... if you miss off the first letter? really? TYPE THE LETTER.

 

you can copy and paste everywhere in the OS in any of the text areas, just long press any text area. the gmail app is missing copy and paste which is a HUGE omission. but for the most part i copy and paste everywhere all the time. and the browser definitely supports it, but not too elegant.
