can cell phones help you manage a healthy, nutritious life?

In today's world cell phones have become a man's best friend. They help us with so many things. I was watching the news the other day when they started talking about diet.com's new mobile nutrition service. This service can help you lose weight by helping you watch what you eat. Suppose you are waiting in line at a fast food place, deciding between two options. You can make the healthier choice by knowing the nutritional information of the two options. you text the name of the restaurant and item to diet1 or 34381 and diet.com will text you back immediatey with all the nutritional information such as calories & fat. I used this a few times and find it very helpful in watching what I eat. Also, there was no extra charge for texting (only the one by my carrier). Here's one example of the cell phone becoming a new diet tool. What do you think.. can your cell phone help you manage a healthy, nutritious life?
