We're just days away from the iPhone 4S launch, and if you've finally decided to take the plunge and upgrade from your year-old iPhone 4, don't worry — there are ways for you to trade up without having to sell your iPhone online. These outlets are trading iPhone 4s for cash, so start planning accordingly.

- Apple — Apple is offering up gift cards in exchange for iPhone 4s in working condition. Exchange values will vary depending on scratches, battery charges, and whether you've supplied the power cord.
- Nextworth — Get cash for your iPhone 4 through this company that accepts phones via mail and sends you payment via PayPal or check.
- Target — Target is also working alongside Nextworth to offer customers trade-in values at their mobile locations or online and payment in Target gift cards, which can be used to buy the new iPhone 4S in store.
- Radio Shack — The Shack offers in-store trading in exchange for cash value, or you can choose to complete the trade-in online, which will garner you a Radio Shack gift card, which you can use toward the purchase of a new iPhone 4S.
