Verizon question

If you are not eligible, then you are in a contract. So you can, but you will get a new number and have to pay a early termination fee to break your contract.


You can always add a 5th line for 9.99 a month to get the i4S at the new pricing then switch the phone to one of your existing lines that wants the phone.

 

(Edit: AT&T story. Verizon may have more common sense)
That's not 100% certain. I had a line once that was not in a contract, but not eligible for an upgrade. I complained and complained, but they weren't able to use common sense and give me an upgrade. I had added the line and never gotten a discounted phone, but the upgrade date was still set almost two years in the future. I canceled the line and added a new one.
