How to Delete All iPhone Data without Restoring?

I might sell my iPhone 4 and buy the new iPhone 5S. So the question is how can I erase all data without having to restore? i dont have many apps downloaded, only some free games, and none of the paid ones. I can delete all my mail accounts, but will it wipe all emails/contacts? Thanks in advance!

Many people choose to resell their old iPhone and purchase Apple's next generation iPhone. But before you sell or trade-in your iPhone, it is extremely important to erase all the personal data you saved on the old iPhone. You will never know who will get your sold iPhone and what he will do with your private data. However, many people ignore this issue and sell their iPhones without erasing personal data.
