Finding a cheap Apple iPhone, therefore, isn’t as easy as you might like it to be. You might be able to purchase an original iPhone off of someone who has upgraded to the iPhone 3G, though, for less than the original price. However, you may be stuck with a particular carrier if the iPhone you buy isn’t unlocked. In that case, you’ll have to buy a contract with that carrier. If you manage to find a cheap unlocked Apple iPhone, you can get around that issue, but unlocked phones are rarely cheap.

There’s also the issue of buying a used iPhone. You never know what exactly has happened to the iPhone you’re buying. It could have been dropped, kicked around, sat on, or any other thing. While it’s a cheap iPhone, it’s also one that may have taken some abuse. Just keep that in mind when purchasing a used iPhone, and be sure to do the math. If you sign up for a three-year contract, you may be able to purchase a new iPhone for just a bit more than a used one.

In fact, one of the best ways to get a cheap Apple iPhone is to sign up for a contract. If you agree to a long-term contract, you can get your iPhone for less than half price. Even better, this iPhone is brand new, so you know it won’t have taken any prior abuse. However, it will most likely be a locked iPhone, so you will be stuck with that carrier. You may have the option of getting the phone unlocked once the contract is up.

Either option can result in a cheap Apple iPhone. It just depends on whether you want a used phone or if you want a new one with a contract.
