I recently took advantage of verizon's site error and was able to upgrade while keeping unlimited data. The only caveat is that I stole another lines upgrade, a line that has the 2gb data plan. I worry that when my line is due in a few months and that line will take my upgrade, will I then be forced off unlimited data because they're taking my upgrade? Some reps have said yes and some have said no. Any experience or know-how about this is appreciated!
