I have two phone lines. One line is the 4, other line. I don't use it at all. The 4g line is not eligible to upgrade for the 4s, obviously. But my 2nd line can. When i check out, it says all the things i have to add, the data, insurance etc.... I just want to upgrade the 2nd line to get the 4s, and change the card to my current phone line for the 4gs. BUT my 2nd line, will bill me the $25 for the 2gig data etc... How do i get rid of it? This has happend to my past, when seeing a $160 phone bill drove me off the wall.
