A more mobile-suitable version of Google, tailored with BlackBerry's track-wheel or trackball in mind, comes as a pleasant surprise. The new Google Mobile App for BlackBerry is installable through m.google.com. As an application unto itself, it's actually a very tiny entity whose real function is to provide a shortcut on your applications menu. It then serves as portals to other Google Mobile apps such as Docs, Calendar Sync, Maps, and Gmail.
If you happen to be one of the few people using an unlocked BlackBerry, then Gmail could conceivably be one viable way for you to get e-mail on your handheld that's synchronized automatically with e-mail you can read from your PC, or from almost anywhere else with a Web browser, for that matter.
But for most, whose e-mail accounts are generally synchronized with their corporate servers or with BlackBerry's own servers (which was the original point of owning a BlackBerry), Gmail may be a minor convenience though not a major feature.
