You will need to downgrade if you have the SHSH. I don't think Ultrasn0w Fixer works on 6.1 yet

On 6.0.1 you will need Ultrasn0w Fixer. Add the source for it.

You need to make sure you have a compatible baseband as well.

Just want to add, if no SHSH saved, you can always restore it back to 4.1.

You will have to create a custom 4.1 firmware (use sn0wbreeze, it's pre-jailbroken and choose simple mode)

Please check the FAQ, Procedure's all in there :)

You never update iOS until an unlock is verified and working just food for future thought
