Google Maps for Android just received a slight update that includes adding ‘check in' and review buttons to Place pages, an option to edit addresses for Latitude, and redesigned transit station pages.
The new transit station pages are especially nice as it's easier to plan your route. The page now has a list of scheduled departures for different lines, all the trainsit lines serving the station and links to nearby transit stations too. Download the update here. Android 1.6+ [Google Mobile Blog]
