I usually get a new phone ever year and sell the current one. I would rather get more money for it because most phone are considered old tech 6 months to a year later. I couldn't imagine trying to sell a 3 year old phone, even 2 years old. I have had the Hero, Evo 4G, Evo 3D, Sensation, Nexus S 4G, Galaxy S2, iPhone 4s and now the Maxx. I got pretty good money for all of them too. Will be selling the Maxx as soon as the HD comes out.
