I got my packet and called in about it to seeif upgrading to I-phone to go now or wait, currently have a BB curve so I get that free. I asked about I-phone upgrade, rep told me take the free phone as it is mine, I have 30 days to decide to upgrade or opt-out and go with Verizon as he said that's who he has (guy was in the Lebanon center, I asked) if I upgrade to the I-phone then I keep the BB as a backup, you don't turn these in when you upgrade it's yours to do with as you please with you own it. He said you can switch the SIM card and use BB at work or whatever and then swap to I-phone when you come home, as it doesn't affect you plan, phone won't work without the SIM card and same plan applies to each SIM card.
