Edit the postbit or postbit_legacy template. Which you should edit depends on which you use. Find where the number of posts, location, etc is listed within the postbit and then add this:

              <div>
                      Whatever info: $post[fieldX]
              </div>

If you want to limit it so that the field will only display if they've filled in their profile, then it would be this:

              <div>
                  <if condition="$post['fieldX']">
                      Whatever info: $post[fieldX]
                  </if>
              </div>

That second one keeps you from having a bunch of users who simply have blanks in their postbits if they haven't, to use your example, filled out what type of cell phone they have.

Change the X to whatever field you want to display
