Hello SRIRAMASHOK and welcome to the BlackBerry® Support Community Forums.
In order to use the wireless contact sync with your Gmail™ your device software must be 5.0 or higher.
You can check for a software update by going to www.blackberry.com/update on a computer.
Alternatively, you can use Microsoft® Outlook® if you are able to export your Gmail data to Outlook.
