If you didn’t sell your iPhone 4/4S before the announcement of the iPhone 5, you’d better do it soon before its value drops considerably. Reports have already come in that iPhone trade-in prices have started to drop on most major iPhone trade-in sites.

In the two days since Apple announced the iPhone 5, values on used iPhones have already dropped as much as 8%. Once the iPhone 5 hits shelves next week, values are expected to drop even faster.

Upgrading to the iPhone every year is costly, but if you keep your iPhone in great condition, you can always sell it right before the next iPhone comes out and use that to supplement the cost of upgrading.

Knowing the best place to sell your iPhone can be the tricky part because there are dozens of places you can go to as each vendor is different and will  offer you different methods and prices. Here are the best places to sell your iPhone now so you can get an iPhone 5.
