Under General settings there should be an option to turn on auto fit. This allows you to pinch and zoom
Edit..just checked and my gmail is version 4.2. I am using Roman's gapps from goo manager.
Under "About Gmail" says I have Version 4.2-478. There is no auto fit option under general settings. Using the gapps linked in the OP, and Sourcery 3.2.
???
Edit. Apparently doesn't matter. I now have pinch to zoom. When the heck did that happen???? LOL
