I recently saw a Walmart flyer advertising that Straight Talk has a new phone, the Samsung T401G. I would assume the g at the end of the phone's name would mean that the phone uses the GSM network, so does that mean this phone wouldn't have the same coverage as Straight Talk's other phones and would not be using the Verizon network? I'm asking because Verizon is the only major cellular provider that has coverage in my area and I'm wondering if I should expect this particular phone to work where I'm at.
