I am ready to purchase an iPad 4 but am not sure whether or not to wait for the 4G model. I have mobile hotspot with my Verizon account so I know I can use my smartphone to access the internet on the iPad. My question is can anyone tell me if the internet access speed will be the same whether I use a wi-fi iPad and a mobile hotspot or use a iPad 4G? If I buy the iPad 4G it will be on my same Verizon account so either way of connecting would be using the same internet access. I just don't know if I will lose speed going from the phone to the iPad vs accessing directly on the iPad. Thanks.
