Hi guys. I jailbroke my iPod Touch 4G using Limera1n beta 1 - all is working great. I backed up my SHSH blobs using Umbrella, and thus I just have one simple question: - On Twitter, I read something about my JB being overwritten if I update to the latest firmware. Will my SHSH blobs allow me to update, yet still preserve my JB? - When a new firmware update is released, will I be able to jailbreak this firmware version using Limera1n as well? In short: What are the advantages of saving the SHSH blobs in the long run? Thanks!
