Currently on eBay or Facebook Marketplace, you’ll likely be able to find an iPhone selling for less than $1,000. But if it has the TikTok app — which you can’t currently download from U.S. app stores — prepare for sticker shock.

Social media app TikTok briefly went dark in the U.S. last weekend due to a federal government tussle over its ownership. It’s since come back online, though the app itself cannot be downloaded from Google or Apple app stores.

The iPhone 15 and 16 models generally sell for between $1,200 and $1,500 on eBay. When the app was first banned iPhones with TikTok installed were listed for as much as $1 million during the app's 14 hour blackout, Ukrainian technology news outlet ITC reported.
