Verizon, Verizon prepaid, Straight Talk data coverage

I switched from Verizon to Straightalk when I discovered that Straightalk sold a few phones that use Verizon towers (required in my area). Been a happy camper but you should note that you need to buy a Verizon capable Straightalk phone and when I bought they were limited to 3G and probably a generation behind the latest/greatest. I am unsure but believe that tethering Straightalk phones is a problem. For my use (phone, text, internet surfing) works great.
