How to upgrade an iPhone 4 to ios 5.1 without removing anything?

The iPhone 4 is ios 5.0.1 and I wanna upgraded it to 5.1 without erasing anything... I don't like to upgrade to ios 6 for some reasons....

You cannot update to anything but ios 6.0.1
If you are using the iphone as designed then you will not lose anything as everything should be on your computer.
