Can i buy an iphone without a carrier?

I want to purchase an iphone 4s or 4 but i don't want a carrier… I'm going to purchase straight talk from wal-mart… Its way cheaper for so much more than i have now. But i really want the iphone 4 so i can facetime with my daughter who is out of the country. Is an unlocked phone something i could do… I already know that straight talk accepts iphone so i just need to purchase one.

Sure you can, go anywhere they are sold. You'll pay a hefty premium if you don't get a contract.

You can get an iPhone off-contract at full retail price, which in the US is upwards of $600-700. You won't have to pay a monthly service fee, but you lose the benefit of a substantial carrier subsidy. Hope this helps!

Yes, I did the same thing.

I purchased my unsubsidized unlocked iPhone 4S directly from Apple.com and plugged in a Straight Talk SIM (with their $45/mo.service plan).It works great.
