I have this little service that I haven't figured out how to monetize, FlyerMe.info. Without sounding like an ad, it lets you print the heading of your flyer and a QR code and scanning the code takes you to a mobile-friendly version of the flyer (text and all). At the bottom I use mailto: so you can mail yourself the link from your phone.

I thought this was acceptable because I think most people have their email clients set up on their phone (unlike many people with no desktop email software).
