Create a visual checklist for your employees
Are your employees sloughing off or ignoring your daily checklists? 

 Maybe they are visual learners and cannot appreciate what an awesome 
checklist you have created. Send them the lists with visuals of what the 
end result of each task should be.
Create instant testimonials
Got a super happy customer that just made a purchase? Ask them 
if you could take a picture or video of them in their excited state.
Have a face-to-face with your employees
Need to have a talk with one of your employees but you are both in different cities or countries? Instead of a text message, why not use your phone to host a video call? Mobile apps like Skype and Google Hangouts make it easy (and free) to have a quick video conference with someone.
Document your belongings before you travel
Have you had your luggage take an unexpected trip at the airport? 
Before you head out, take a few minutes to snap pictures of your
 luggage, and it is unbroken contents. This will help if you need to produce
 an inventory at some point.
Take pictures of your business cards
Got too many business cards floating around your desk, glove compartment 
and wallet? Why not use your mobile camera to snap and store them digitally?
 Use an app like like CamCard to scan a digital version of a business card and
 add detailed notes for a later follow up.
Send product images instantly to potential customers
Got a customer calling or emailing you asking about a new product? Take 
a snapshot of it with your camera and email them a visual while you are still 
on the phone to increase your chances of making an instant sale.
