Cell phones have become a necessary part of daily life, and with the advent of the smart phone they are only becoming more of a daily fixture. Every month or so a new model comes out that has faster processing speeds, updated features, and the coolest new applications that many feel they absolutely need. Because of this, the average shelf life of a cell phone is 18 months, which leads to 100 million phones being replaced each year and at least two million ending up in landfills each week.
