    Hi!

    I have been looking through all of the posts and forums here and want to verify some information. I have an iPhone 3GS, firmware 3.1.3, baseband 5.12.01, bootrom 359.3.2 and jailbroken with Spirit. I want to upgrade it to I'm thinking 4.1 since it is the newest available and I want to upgrade before 4.2 comes out.

    I downloaded pkgbackup from cydia, ran it and synced through iTunes again. What I want to be sure of is what to do next. The Spirit JB was the first jailbreak I have done so I don't want to mess anything up going from one jailbreak to another. When I open Cydia I find SHSH: iOS 3.1.3, 4.0, 4.01, 4.02 and 4.1 at the top. I get a little bit confused about whether or not I need my SHSH blobs or if I can just upgrade to 4.1 with the configuration I have and then jailbreak again. I don't know if I can just upgrade with the iTunes update or if I need to download a certain firmware from somewhere else.

    From what I understand I need Limera1n or Greenpois0n to jailbreak 4.1 so I also want to be sure of that. Also, if it makes a difference, I don't have my phone unlocked and don't need it to be because I have AT&T service. I am pretty good at figuring most of this out but I want to make sure I don't do something incorrectly and brick my phone. I would like to have help moving to a newer jailbroken firmware and then the next time I will know what to do on my own. If anyone could help me with what to do from here I would appreciate it SO much! Thank you in advance for any help I get!

    Update itunes and hit restore to take you to 4.1 and jaibreak with GreenPoison or Limera1n.
    Setup as a new iphone. Once you have jailbroken your iphone, install Pkgbackup and then sync your itunes, hit restore from pkgbackup.

    Easy as that? Nice! Now, one more thing. Does there seem to be any preference among users for Limera1n or Greenpois0n? Is one easier then the other? And BTW.....thanks for the fast reply!

    I now have a functioning 4.1 jailbreak! I had no problem at all using Limera1n. I had a little trouble getting all of my apps back on with Pkgbackup but I figured out what the problem was and I am fixing it as we speak. Thanks so much for your quick replies and your help!

    I only needed to jailbreak my phone so I can't help with the unlock but maybe someone else can.

    Perhaps one could use sn0wbreeze to create a custom IPSW that prevents the baseband from being updated. Then one could install the latest ultrasn0w unlock and be able to use the phone on different carriers.

    Hi there my situation is exactly like the poster except I have an unlocked, jailbroken phone, 3.1.3, fw 5.12.01 with new bootroom. When I got it last summer I had to wait for the right files to unlock and JB. but would like to upgrade to 4.1 or 4.2 if I can. thank you in advance. I am somewhat of a n00b...just a warning...

    You need to find out what SHSH you have with tiny umbrella and what bootrom you have with idetector first.

    When I used tinyumbrella earlier today because I tried to update and it went into recovery mode so I had to use tinyumbrella to get my phone out of that mode. I will try tinyumbrella again to find the SHSH, I know on my cydia it says iOS 4.0, 4.0.1, 4.1

    I have the new bootrom and I have 4.0, 4.01,4.1 and 4.2.1 shsh files

    If you want to stay unlocked you need to use snowbreeze or pwnage tool to make a custom 4.1 and restore to that in iTunes.

    Okay thank you for the speedy reply. So first I get snowbreeze then get the ipsw for 4.1 and then "shift click" on restore in Itunes to that 4.1 ipsw??? Just clarifying, I can think its one way and its completely opposite. thank you


    Is it the snowbreeze here? http://modmyi.com/forums/general/698...-download.html
