I had the same problem - I only saw the "mobile" mode of gmail on my 7130c. I didn't see where I could change or select anything else like "basic HTML". So, after the internet browser was launched (not the cingular browser as mentioned already), then go to options, select browser configuration and change emulation mode from blackberry to internet explorer.

Now, go to gmail. It should load up as if you're on the regular internet (i.e. basic HTML) instead of in mobile mode. Now scroll way down to your messages, select the appropriate message & scroll down again to where you see the attachment. Now you should see "scan and download". It loads into the BB audio player & you can now save away.

BTW, I'm on BES & I can also get to gmail html no matter how my blackberry browser is configured. So, I don't completely understand the differences between the BB browser on BES vs. the cingular browser (aka MediaNet) vs. the internet browser, but the above definitely worked for me.

Good Luck!
