Description:
David Safai shared in an interview that when people upgrade, they usually believe that their old phone is worthless and they either keep their old phone in a drawer, donate it or just throw it away and there are 61 percent of U.S. adults in this category who think like this. In addition to this, he also told that Mobixa is the only online Smartphone upgrade advisor service that offers a top buy back price for iPhone 4S and pays around $300. – PowerPoint PPT presentation
