Compared to the latest Asian cell phone technology, the US cellular products look antiquated. Japanese carrier NTT DoCoMo's new 901i series phones are capable of four-way videoconferencing and high-speed mobile Internet surfing.

They can operate as TV remote controls,
at least two-megapixel cameras, have miniature "3-D sound" speakers, act as a fingerprint sensor, or a digital wallet.

There are several reasons why the US doesn't have these phones, yet, but the main reason is that the cellular network is a mess and can't provide 3Gig or 4Gig networks that are required at this time.
