If you havent already seen, verizon launched their 4G LTE network. I read that technically this network is 3G, and that LTE is a GSM network. So isnt it possible that the verizon iphone, will still be GSM but will have "4G"?
Yes and No. LTE is SIM card based but runs on a different band than the current 3G network run by AT&T. As far as it being a GSM radio, that is yet to be seen.
