The wait is over for Android users who want pinch-to-zoom capabilities for their mobile Gmail apps. Android Police reports that Google (GOOG) has released its new Gmail 4.2 app that will be available for all devices with Android 4.0 or higher. The new version of Gmail, which we first learned about in October, lets users zoom in on their emails with a simple pinch gesture and also gives users the option of deleting or archiving their emails with a simple swipe gesture. Android Police says that other additions to the app include “in-app video and photo attachment capability, and larger photo previews, along with a brand-new gallery view for emails with multiple image attachments.”
