If you have a cell phone that can go on the internet then you can probably access your iGoogle page with the same up-to-the-minute information you have on your desktop iGoogle page!
Just point your web browser to the following url:

Which phones work? Most Blackberries, any phone with Windows Mobile, the iPhone, many Nokia phones.... actually -- most phones today have internet access. Make sure you have a data plan (unlimited to be sure) so that you don't incur needless charges.
