This thread just serves to show that Kyouhei's iPhone 4- which he only had SHSH blob 6.1.3 - can be downgraded to firmware iOS 4 - 6 without blobs. This applies to ALL A4 devices.
The difference here is the current GeekGrade firmware locks up the device after a period of time.
Kyouhei can verify the serial number. - here take a PM from when I was asking about the phone before buying it -
bowser - you were interested.
Once I get the kinks worked out I will release my personal version of the firmware- with fixes and Cydia for iOS 4 and 6.1.3.
