[Gmail-Users] Google mobile: access error: invalid page

Web page: http://m.gmail.com/
Mobile used: Motorola RAZR V3
Service provider: Hutch GPRS in India

I am getting a page with the following content:

(links to google, login, etc.)

The page you have requested is invalid

(other links - privacy, etc.)

Any idea why this is happening?

Thanks,
Sankar
