Japanese carrier NTT DoCoMo unveiled a bunch of new mobile phones in the 706i and 906i series. The 706i line includes the new F706i water-proof 1Seg digital TV mobile phone.

As you can see in the photo you can watch TV with F706i underwater. When would we need that? I cannot even open my eyes underwater without goggles.

All in all NTT DoCoMo introduced 19 new phones.
The 906i series' eight handsets are equipped for all-round functions, including 3G/GSM international roaming, upgraded GPS location information, HSDPA, "One-Segment" mobile TV, 2 in 1 (combines capabilities of two phones in one), DCMX mobile credit card and iD mobile credit payments, VGA LCD screen, and voice-to-text translation for Chinese, English, and Japanese.

The new 706i series, 11 handsets in all, boasts slim, sophisticated designs and compatibility with "One-Segment" mobile TV. The 706i meets diverse needs with a wide-ranging lineup, including the Extra-Slim One-Seg Phone (slimmest One-Seg phone available), the Waterproof One-Seg Phone, the Wellness phone that monitors diet and health, and the enhanced Easy-to-Use phone with improved user interface. Some models are also compatible with advanced services such as HSDPA and 3G/GSM international roaming.
