According to the Official Google Mobile blog, the Google Mobile App has been updated and you can now search your email and contacts from the app using Google’s advanced search engine. The app lets you type or speak your search query and Google Mobile will search through your emails and contacts and return the results. You can then reply to an email or forward it, depending on what you want to do.
Google Mobile also lets you quickly call, SMS, or email contacts by typing the first few letters of your contact’s first or last name, and then pressing the corresponding button. The app will suggest contacts as you type and you can scroll down to select one. Google Mobile will even promote the people you contact frequently to the top of the suggestions list.
Searching email requires BlackBerry OS version 4.5 or higher. Searching contacts is available on BlackBerry OS 4.2 and higher.
To download the latest version, go to m.google.com from your device.
Speaking of Google, they might be shutting down their China operations. I highly recommend reading their blog post on the subject.
