【Watch The Hills Have Thighs (2010) full movie】

Apple is Watch The Hills Have Thighs (2010) full movieexpected to reveal three new iPhones at its Sept. 12 "Gather Round" event.

They're not going to be cheap — luckily, if you bought an iPhone X, you can trade it in to get cash or a gift card to put toward your new device.

First off, you'll want to know the condition of your device, the model, and the storage size. Go to Settings > General > About to see the model number and the storage size of your iPhone.

After that, check out the top trade-in sites to see which one will give you the best deal.

Gazelle

You've likely heard of Gazelle, which will pay you for your device via check, PayPal, or an Amazon gift card. Keep in mind you won't get anything until Gazelle has received and inspected your device.

The payout for an unlocked 64GB iPhone X with no cracks and a working screen should be around $500. An unlocked 64GB iPhone 8 Plus will get you a bit less ($450), while you'll only get $350 for an unlocked 64GB iPhone 8. Once you decide to sell your phone, print out a shipping label or have Gazelle mail you a box so you can ship the company your phone.

BestBuy

Like Gazelle, BestBuy accepts iPhones dating back to the iPhone 5. In return, you'll get a BestBuy gift card.

For BestBuy, you'll want to make sure your device is unlocked, and know the condition on a scale of broken, fair, or good. A 64GB iPhone X in good condition that's unlocked will get you a $510 gift card. An unlocked 64GB iPhone 8 Plus is worth $425, while an unlocked 64GB iPhone 8 will fetch $340.

BestBuy's trade-in program is a bit tougher than Gazelle's, as your device needs to be unlocked or you'll get very little for your iPhone, if anything at all.

Apple GiveBack

Believe it or not, Apple also has a trade-in program. You can get an Apple gift card, or the company will recycle the device at no cost.

Apple's GiveBack program currently doesn't accept the current generation of iPhones (8, 8 Plus, or X). However, Apple will take the iPhone 5, 5C, 5s, SE, 6, 6 Plus, 6s, 6s Plus, 7, and 7 Plus.

An iPhone 7 Plus with a working screen, no scratches, and in overall good condition should get you a $290 gift card.

It's likely that Apple will start accepting the iPhone 8, 8 Plus, and X at some point in the coming months.

MyPhonesUnlimited

MyPhonesUnlimited is a newcomer in the trade-in game that offers decent payouts.

You can trade in iPhones dating back to the iPhone 4. MyPhoneUnlimited pays via check about a week after they get your phone. (It'll send you a box to make shipping easy.)

An unlocked 64GB iPhone X in good condition is worth $490, an unlocked 64GB iPhone 8 Plus worth $370, and a 64GB unlocked iPhone 8 worth $320.

Now that you're ready to sell your phone, check out Mashable's coverage of Apple's big iPhone event to see what you can buy with the money you make.
