Long press on the text (you should then get tabs that you can pull to highlight more text). At the bottom of the screen (next to "select all") there is a copy button (looks like 2 documents) - press that and it copies the selected text and then go to where you want to put the text and long press and it will show "paste" - touch that and your text will appear.
Hope that helps... let me know if this doesn't work for you and I will see what I can find on the net for you!
