Does anyone know of a way to restore a phone 4 while keeping it on IOS 6.1?
Would like to use it as a dedicated iPod.
I could do a normal iTunes restore (bringing it up to its highest possible firmware of 7.1.2), but from what I've heard the iPhone 4 runs much better on IOS 6.xx...
you've got shsh blobs for iOS 6.1 so you can use a program like ifaith to stitch the SHSH blobs to the ipsw to create a custom ipsw
put the device into pwned DFU mode
open itunes and shift + click restore (windows) or alt + click restore (mac), select the custom ipsw and restore
if you don't have shsh blobs, you can use ifaith downloaded from ih8sn0w.com to dump the blobs for your current iOS version
please note that you only have this option because your iPhone 4 has a bootrom exploit availiable
