Hi guys. I jailbroke my iPhone 4S with Absinthe and I'm wondering if I want to update to 5.1 when it comes out later can I just do a regular update using iTunes (or even OTA update on the iPhone) without going through the complicate process of using Tiny Umbrella and whatnot? I don't plan to jailbreak my iPhone 4S in the future so I just want to get it back working as normal. Would updating through iTunes brick my iPhone? Thanks!
