Whereabouts are you from? http://xnxxxnx.in.net/ xxxx The growth in the market for used phones is due in part to increased awareness among consumers about trade-in programs offered by carriers and cell-phone resellers, including Amazon and Gazelle, as well as increased resales on consumer marketplaces like eBay. The NPD Group said this week that half of the U.S. smartphone users it surveyed said they would take advantage of trade-in programs the next time they upgraded, a move that has the potential to shift loyalties away from carriers and retailers. Apple is reportedly planning on offering its own trade-in program through its stores sometime in the near future.
