I installed this last week, if you’re a Gmailhead and have a dataplan on your phone (almost everyone does now,) get this. You’ll love it!
Before installing this I use to use Gmail’s mobile site for checking mail. This program lets you open images, PDFs, and MS Word files (I’ve tested it with pictures and Word docs.) You get to see things in discussion view. It downloads messages in their entirety and is really friendly to use.
Another winning app from google.
Note: Alhough it’s relatively cheap. Using data on your phone costs money. find out how much money before you go nuts with having a sweet mobile Gmail app.
