I am not elgible for an upgrade until June. My girlfriend and I are on same plan and she isn't due for one even longer than that. I called Verizon this morning and told me I could add an additional line for 10 extra dollars a month. The problem is, I don't need an additional line. How much of a headache is doing this, how exactly does it work, and how expensive is it to get rid of that additional line once I upgraded my 4s to the 5? Are there any other methods to getting the upgrade price ? Thanks in advance.
