If I update my jailbroken iPhone will I lose my jailbreak?

I jailbroke my iPhone on ios 6.0.1 and I just want to know if I update to 6.1 will I lose my jailbreak? (Evasi0n does support 6.1 that's what's confusing me)

Yeah you will lose the jailbreak if you just straight-up update it

Yes you do loose everything.
When updating your iphone/ipod the new software clears everything from your device so it will be able to add the new things that the update comes with.
To prevent loosing your games etc.
Just save everything to itunes. I did this and i did save all my pictures and games apps.
Just make sure you do safe all those stuff into itunes before updating the device
