I have an upgrade at Verizon and i want to get the new Iphone?

So I have an upgrade at Verizon and I have been waiting to get an upgrade for the new Iphone 5 to come out. Now I'm finding out that if you want the Iphone 5 you will have the change your plan or pay 650 and keep your plan! Let's say that I get a upgrade with a different phone like the Galaxy 3, do I have to change my plan too or is that just with the Iphone or is Verizon making all costumers change over from their unlimited plans? What should I do?

Go with a android because the iphone is expensive, unless you want to pay that. You won't have to change your plan

If you want a phone at the discounted price, you have to switch to the new shared data plan

if you don't want the shared data plan, you have to pay FULL price, no matter which phone, the Galaxy S III, the Droid Razr, the iPhone, or any other smartphone.

I want to buy iphone 5 from verizon wireless shop ryt nw i amin india can you please help me if youhave any experience with verizon?
