I bought a 4s off craigslist today. Its running off IOS 7.0.6. Since the firmware is relatively new, has no one found a way to downgrade yet? Also, has anyone developed something to unlock a jailbroken iPhone running 7.0.6. either? (cydia, redsn0w, etc.) I've been looking through everything for hours, no luck. Assuming because it's too new.
