iPhone TV: Apple's amazing iPhone does just about everything, right? Nope. It's come up short in Japan for various reasons, including its lack of the TV function available on the newest generation of mobile phones.

Softbank is tackling this shortfall with a new gadget that works with an iPhone and allows it not only to pick up 1Seg TV broadcasts but also pull double duty as a battery booster.

The unit includes a TV tuner and aerial and it retransmits the signal via Wi-Fi to the iPhone, eliminating the need for a physical connection, unless you need the battery booster. Users will need an extra software application, but that will be available free of charge when the device goes on the market in mid-December.
