I believe it's safe to say at the very least, this will be a CDMA, 3G device, since that's what all of Verizon's other phones are
To LTE or not LTE - that's the question... I'd be amazed, and more than a bit irked if this turns out to be an LTE only device... I won't likely have VZW LTE coverage until sometime in 2012 in my locale.
