I just jailbroke my iphone using Limera1n. If I want to upgrade my firmware from 4.1 to 4.2 (when it comes out), what do I do? Do I need to restore my phone and then jailbreak it again using the same method? I've saw Cydia will be upgrading to support OS 4.2 as well, what does that have to do with everything? I'd Really appreciate if you can post me some instructions! Thanks in advance.
