Can I get an iPhone 6 even if my contract has 6 months left to get an upgrade?

I have had my iPhone 4 for 1 and a half years and I still have 6 months until my contract expires and I can upgrade to a new phone. I really want an iPhone 6 because my phone is extremely slow and glitchy and it's really a pain. Is there any way I can get an upgrade without having to pay a fee to buyout of the contract. I'm a Verizon user and would continue with Verizon with a new phone.

I think it is possible with some couriers to be able to pay a fee, and you'll be able to 'finish' the contract and upgrade.

Yes but you pay full price

Switch to US Cellular they pay off your old contract
