Please help with Galaxy S5 questions

[pego99]

I am trying to buy a new Samsung Galaxy S5 on ebay.
All the units for Verizon say Verizon but also say GSM unlocked.
I thought Verizon is CDMA technology.
Is model SM-G900V the correct model number for the model that Verizon supplies to it's customers for USA use?
If I update the GS5 to the latest software will towelroot still root the phone and will the paid Foxfi wifi tether app still work?

Thanks in advance.

1st, that is the correct model, and yes the 900V will work on GSM.

And no, if you update the phone, towelroot doesn't work. But I've heard rumours there is a way to do it now, but it is not quite as straight forward as it used to be.
