Is there anyway I can update my iPhone without a computer?

IPhone/iPad or iPod Touch's iOS software can be updated without the use of a computer or iTunes. This is also called OTA or Over the air update. This can be done on any device running iOS 5.0 or over. You will need to be connected to Wi-Fi and have at least 50% battery or you will have to connect your device to a power source.

THIS Can't BE DONE ON A JAILBROKEN DEVICE! Don't even try, it won't work.
