The 2012 mHealth Summit near Washington, D.C., is where mobile technology and health come together. This week's 20th anniversary of the text message really highlights the critical marriage between the two sectors. The first message was sent through the Vodafone (VOD -0.34%) network, and Nokia's (NOK -0.81%) phones really helped texting take off.

However, the ubiquitous text message is still important. The summit featured experts from UNICEF, Johnson & Johnson (JNJ -0.69%), and Verizon discussing how texting continues to save lives. See more in the video below.
