Google Mobile Updater will keep you notified of new Google Mobile services as well as updates to installed applications.

Apparently, to get one you need to go to mobile.google.com and click on "Get Google's mobile products in a single download". But what Google products? Search, Maps, Gmail, News, Picasa, and Reader.
While Gmail and Maps are already available as mobile apps for most phones, it's not clear what you can expect from the rest of the services and if they're more than simple links to Google's mobile sites. So if you have a Blackberry and you want to finish this post, please do.Google, BlackBerry, Google Mobile, Google Mobile Update
