Can I buy the new Iphone 6 without a contract?

I already have a contract with AT&T but I'm not eligible for an upgrade. I'm willing to pay full price up front.

Added (1). Also, where should I go to buy it if possible?

Yup. I believe they will even let you just transfer phone number's contract to the new phone.

You can but where will you find it? It's back-ordered everywhere. Only way to get it now is from resellers and dealers and they'll charge you more than the retail. If you need iPhone 6 without contract at reasonable price, mail me.

Of course you can. You will be waiting a while now though as they are sold out.
