How to update my iPhone to ios6?

I have a jailbroken iPhone 4 yes I'm getting the iPhone 5 so I just jailbroken this iPhone and now it's stuck on 4.3.1 is there a way I can update without iTunes because I'm to lazy to bring my desktop upstairs and it is packed in the garage.

Ios 6.0 comes out in september 19
i'm waiting for it too… Want to use siri right now! Lol

You need a pc, get the ios 6 firmware.search youtube for it) then hold shift in itunes and click restore and choose ios 6 firmware.

I already have it from beta Haha

Nope. 4.3.1 doesn't have OTA (over the air) updating so you will need a computer.
