I think I should 1. Activate on another line even though I upgraded during the "Unlimited Glitch" just to be safe. I have a throw-away line that I use for upgrades but it won't let me activate anything to that line at the moment. I may have to activate it on my mother-in-law's dumb phone line for the moment. Once I open the package, If I see that it does indeed still say unlimited data, I can activate it on the line I bought it one (It had a Galaxy s4 with unlimited data) and then just switch phones back to the S4 right after. 2. Sell it and ask the buyer to meet at a Verizon Store so they could have it transferred. If they are an AT&T or T-mobile customer, do I need to even do this? Also, do I need to physically open the phone at all to perform any steps? I'd rather sell it sealed and open it in front of them once they pay me. Should I take out the SIM card after I sell it to them? Also, if anyone can just point me to an existing thread that goes into these details very specifically, I would appreciate that just as well. I searched for 30 minutes and could not find such a thread anywhere.
