I have the ipad 2 16 gb and i have a question about the network. Okay well i could use the internet at my house and even outside my parking lot but then when i start going far more i lose it. My sister has the new iphone and she told me i could use the internet by putting the name of the network from her iphone and that i will be able to use the internet while im at the store but i have to be by my sister. Is that true? If so how do i find out the name of her network from her iphone and the password? Thanks in advanced
