HTC ThunderBolt

Many of us here work in the Wireless Communication/Technology and understand what makes things work. We also watch technology and company product offerings for a living. Trust me.... Verizon tells its employees exactly what it wants people to upsell the latest and greatest.

The dual "intenna" (which I assume is a Verizonism for "dual internal antenna") is required for any 3G/4G phone. This is because Verizon's LTE frequencies are in the 700mhz band (UHF TV spectrum taken from the public by the FCC and sold off to ATT & Verizon for billions). The frequency and LTE signal are quite incompatible, so until there is enough 4G LTE coverage verizon will be selling dual band, dual radio devices for a long time.

The LTE radio won't work on 3G towers, and the 3G radios can't work on LTE towers.

So while it is true that in LTE 4G areas you will have dual And when they gradually phase in LTE voice, you will be able to do the same. And even if they could, you will need to implement changes at the tower side as well.

But for now, take your Thunderbolt and any number of forthcoming 4G phones into an area where only 3G CDMA signal is available, that phone will work exactly as any other 3G CDMA phone.

Don't get me wrong.... 4G is great, and the Thunderbolt has the makings of being a great phone for people who live in the centralized cities where it has been deployed. Those of us in suburbia 100m from 4G coverage will get nothing but dead weight and higher price for at least two more years.
