How to "drop a pin" for iPhone AND Android users?
If you use the iOS Maps Share Location feature via email, the recipient gets a message with a Google Maps link to the specific location, which is openable in anything with a browser (although mobile devices may open it in a Google Maps app). It also attaches
vCard containing the address of the pin and the Google Maps link.

You could also use the email feature to just get access to the link directly, and copy it into your medium of choice, discarding the email.
