The FCC today approved the Sanyo S1, the company’s return to bar phone for Sprint. Like Sanyo’s original bar phones, the S1 is thin - 11.1mm - however that’s not uncommon for current handsets. The S1 is an entry level phone with Bluetooth, no camera is even visible in the initial documents. Sprint previewed this phone at an event last month with indications it is due out before the holidays.
