A software update will enable it?! Seems like we need the hardware 1st. Anyone verify that we infact have a chip that can go 800MHz RevB?
Not to nitpick, but you're combining two separate things.
The 800mhz ESMR band is currently used by Sprint for iDEN, which is its legacy Nextel push-to-talk network. It was announced awhile back that Sprint planned to provision that band for CDMA. So any phones that are capable of operating on that band, which our E4GT is, would immediately benefit, although the benefits are arguably minimal for most customers. But in the end it would boil down to "more bars in more places" for voice.
EVDO Rev B is an evolution of the Rev A technology for the transmission of data. From my limited understanding, moving to it only requires some kind of software overhaul by the carrier, but in order to take advantage of it, a device needs to have the hardware, which from what I've been able to gather so far, the E4GT does not assuming it is indeed using the Qualcomm QSC6085 CDMA Processor.
The EVO 3D does it seems, as the CDMA radio is integrated onto its Snapdragon SOC. It probably helps that Qualcomm created the entire SOC in that phone's case.
