    I have an iphone 3GS that was jailbroken by purple rain and is currently running 3.0.
    I wish to upgrade to jailbroken 4.1.
    Should I upgrade via itunes and then jailbreak using green poison or limerain.
    What are the negatives of this method? What other methods can I use?
    What is better to jailbreak with green poison or limerain?
    I am not sure if i have any shsh files with cydia. How do I check this?

    Thanks for your help

    You can use tiny umbrella to check what SHSH you have. If you do not require a unlock then just update to 4.1 with itunes, then use greenpoison or limera1n to jailbreak.

    Then you either need to use the new pwnage tool or sn0wbreeze to create a custom 4.1 and restore to that.
