There are some good HTML add-on applications your friend with the BB can use. I use Empower Pro HTML Mail Viewer, available at
Empower your BlackBerry with HTML Email Viewer and BES MailBox. Lots of people also like BBSmart HTML viewer,
BBSmart - Software for your BlackBerry®. Now that I can read HTML emails on my blackberry, I can never go back to text only. Empower has a free 30 day trial on the std or pro versions at getempower.com/ota. She can type that into her browser and go straight to the download link.
Good luck with your crackjack.
