    hey this may be a newbie question but, is there a way I can for a fresh restore of my iphone without updating to 3.1.3? I have the 3.1.2 update file but because itunes is connecting to check for updates it keeps saying that I have to update...

    how can I do a fresh install of 3.1.2?

    If you have a 3GS, you can only restore to 3.1.2 official if you have saved your 3.1.2 SHSH either on Saurik's server through Cydia or locally using Umbrella. If you have done neither of these things, you cannot restore your phone to 3.1.2 official. If your phone has the old bootrom you may, however, be able to jailbreak your phone at 3.1.2 and then restore to a custom 3.1.2 firmware made with PwnageTool.

    If you have your 3.1.2 SHSH on file in Cydia (as in the following image), then you can shift-restore to 3.1.2. Otherwise, you cannot.

    Have 3.1 on 3GS Jailbroken Boot Rom 5.11.07

    I have had this phone jailbroken for 2 months, all of a sudden the battery drains really fast (within 3 hours)

    I have been told restoring is my only option to fix this issue but I dont want to go to 3.1.3

    In Cydia it states This Device has SHSH for 3.1.3

    How do I get out of this mess???????

    Yes, nothing for the moment.
    Wait for a new JB hopefully soon.
