eBay may like the idea of serving as a storefront, but it knows that this only works if it helps you sell your wares at the same time. That's where the company's reworked, version 4.0 mobile apps come into play -- the version 4.0 update for both Android and iOS gives auctions higher priority than they've had in the past. It gives you more help when you're a first-timer, a dashboard for frequent sellers and an overall simpler, faster interface for selling your goods. It's an acknowledgment that many eBay auction holders might prefer to run most (if not all) of their businesses from their phones. You shouldn't have to retreat to a computer just to sell your old gear, should you?
