Softbank is already in the news for offering built-in mobile TV receiver for the Samsung Omnia; here comes another stomper from the same firm, but this time for the iPhone. The local telecom corporation is offering a 1Seg TV tuner add-on for the iPhone 3G that will be area restricted, i.e. the application will be available in Japan only. No hidden fact that the iPhone isn’t as great a hit across the eastern coats as it is in the western countries, hence this could be a fruitful ruse, resulting in acceleration of the sales-rate of the handset across the region. Business talks apart, the add-on turns your iPhone into a mobile TV via WiFi once you attach the 1Seg/battery-pack to your iPhone through a dock connector. Slightly more compact than the iPhone, the device weighs around 80 grams and comes in dimensions of approx. 2×3.5×0.6 inches. The TV tuner that also works as an extended battery pack is likely go on sale for $100 [10,000 yen] from mid-December onwards, across Japan.
