iOS 7.1.2 Downgrade

[Fee]

Hi all. Anyone know whether there's an untethered method for downgrading iOS 7.1.2 to 6.1.3 on an iphone 4?
7.1.2 is annoyingly slow on the iphone 4. The phone is currently and has never been jailbroken but I dont mind doing it if thats what it takes to downgrade.

Not sure if this will work for iphone 4, they say iphone 4s and ipad 2.
