Newbie: Licensing requirements?

Hi,

   Was just wondering what are the licensing requirements of jQuery and jQuery mobile when use in a commercial but free mobile app such as one built using phonegap? Is it enough to include the MIT license file in the App's binary and/or is it also required to show the license in say About or Credits screen in the App? Is that the way it is typically done and, if so, is there an example of an App doing that way?

Searching the Web yields different kind of answers...and so trying to understand what is the minimum that might need to be done to satisfy the license requirement. Any insights appreciated.

Thanks in advance and regards
