Windows Phone 7 is eons away from catching up with the features that Apple’s iOS offers but it is soon catching up. Users had complained of a lack of copy-paste functionality and it was reported today that Microsoft is working on that issue and a fix was coming in pretty soon that would let users copy/paste.
With the new fix you may highlight a text with your finger and copy that highlighted text and paste it else where. The feature is said to allow users to copy paste text and can even span across applications.
