Hello all, and forgive the newbieness... but I have an ATV2 jailbroken on 5.0.2. I've wanted to upgrade to the newest 'breakable' version, and recently read about 5.3 being available untethered. However, I also feel that in my research, it has stated if you don't have blobs for a specific OS version, the you can't upgrade to it. Am I incorrect in this? Can I upgrade my 5.0.2 using the 5.3 ipsw file I downloaded? I don't mind having to refresh everything - I feel like my ATV2 could use a 'spring clean' anyway.
