When the first Limera1n jailbreak came out after iOS 4.1 was released, I used it to jailbreak my iPhone 4. So currently I am running on iOS 4.1 with a Limera1n jailbreak in place. A couple questions: --How do I know if this was a tethered jailbreak or not? --If it is or isn't tethered, how does that affect if I want to upgrade to a new iOS? --Is there any way I can update my iOS from 4.1 to the newer ones and still keep my jailbreak? --If I am able to upgrade my iOS but I lose my jailbreak, if I re-jailbreak my phone will I have to start over with everything I've downloaded with Cydia? Any help on this would be greatly appreciated. Thanks!
