Getting a new iPhone? Don't forget to sell your old one.

As if you didn't know, the iPhone 4S is released today and already causing queues outside mobile phone shops.  If you pre-ordered your new iPhone it should be arriving today.  But what will you do with your old phone?  Put it in a drawer?  Chuck it in the bin?  No chance!

I'm sure you'll be having way too much fun with the new camera, the new apps and Siri, but if you sell an old iPhone 4G 32Gb it's worth up to £287 today, so don't miss out on that extra cash.
