The iPhone 5 – or maybe iPhone 4S – will emerge at Apple’s special unveiling Tuesday. If you’re thinking about getting the latest iPhone, you might as well earn some money off your aging model.

With the expected release Tuesday of the next iPhone, some owners of the current version of Apple Inc.’s hit phone won’t sit home and grumble. They’ll sell, then upgrade.
Smartphones and other tech gear that are rendered obsolete by the latest version, or just get a little old, certainly are far too valuable to stash in a drawer and forget about. In fact, with an iPhone, you might be able to sell it for nearly the price you paid. But you have to know how to play the “recommerce” game to get top dollar.
Apple is expected to launch the fifth version of its best-selling iPhone today.
Journalists have been invited to a “Let’s talk iPhone” event at its California campus due to start at 10:00 PDT (18:00 BST).
Doubts surround how different the iPhone 5 will be to its predecessor though some do expect big changes.
The launch will be hosted by Tim Cook, now Apple’s full time boss following Steve Jobs’ retirement in August.
As ever with Apple launches, exact details of product features will not be known until the event. Expert opinion is divided with some expecting significant changes.
