How to completely delete everything on iPhone before selling?

I'm going to sell my old iPhone 5 online, but there're many sensitive private information stored in it, i surely deleted but still worry about the possible recovery by next owner, so, is there any ways could completely erase data from iphone without recovery?

Most people suggest doing a factory reset. But it is only the equivalent of performing a 'Quick Format' on your iPhone. All of the personal information is still accessible in the unallocated blocks of the iPhone's NAND memory.
To permanently erase the phone, then you should follow this guide instead: http://tinyurl.com/erase-iphone-completely
