    Default Need to update 3GS from 4.1 to 4.2.1 unlocked and Jailbreak

    Hey Guys,

    Recently bought a second hand 32GB 3GS with 4.1 unlocked and jailbroken. There seems to be battery issue with it which after some research I found out could be due to iOS 4.0

    I am thinking of upgrading to 4.2.1 and see if the problem is sorted out.

    I have loads of questions before I actually decide to go ahead with it. So thought should ask them here...

    1. what are the pros/cons of upgrading to 4.2.1 (I am on new bootrom [iBoot 359 3.2] and new baseband)
    2. Will 3.* work better on 3GS or 4.* ?
    3. I heard with baseband 06.15.00 one can not go to stock iOS.
    4. The best solution for my situation.. I need to jailbreak and unlock with latest iOS possible.

    Awaiting for response as I have 4.2.1 ipsw and redsn0w downloaded and ready to start the process...

    Edit:
    I use windows 7
    SHSH saved with me

    thanks in advance.

    Why do you think the battery problem is iOS 4 related? The only battery issues I know of are:

    third party replacement batteries can cause some iOS restores to fail - because the iOS update wants to also update battery firmware, which is not possible on the 3rd party battery

    Incorrectly configured push notifications (due to using hacktivation or sometimes restoring from an iTunes backup) can cause excess battery drain.

    Anything else is likely a hardware problem.

    Avoid it if you can - until an untethered jailbreak is available. Also avoid updating to 6.15 baseband unless you absolutely need an unlock.

    They work about the same.

    This is correct and especially frustrating for those with newbootrom 3GS and no 4.1 SHSH

    If you have SHSH for 4.1 then I recommend you downgrade to that.

    The combination of 06.15.00 and 4.2.1 is problematic for a number of reasons.
    06.15.00 works much better with 4.1 according to reports I have seen.

    Hard to say, if you have trouble with some stock restores - then the restore log can give clues that the battery is not original. There are not battery firmware updates in every iOS release. So this problem is usually encountered the first time you try to update to a specific new iOS version. I'll try and dig up the thread about this.

    Hacktivation - incorrectly configured push, junk carried over from prior jailbroken iOS versions.

    Unless it's hardware - these are usually fixed by:

    Restore iOS to same version.
    If at all possible, activate with a legitimate sim card and set up iPhone as new.
    Otherwise:
    Option 1 - jailbreak and install ultrasn0w / http://www.hackint0sh.org/f204/194306.htm - use that to activate legitimately - then setup iPhone as new. enable push notifications - then if you don't need them turn them off.
    Option 2 - jailbreak/hacktivate, set up iPhone as new. and install push doctor from Cydia - to get legitimate push certificates, enable push notifications - then if you don't need them turn them off.

    I am currently on 4.1 and having problems with the battery performance.. I want to make sure its not hardware issue..in case it is then I can return it to the person I bought it from. I am basically looking for a fresh install of everything.. jailbreak + unlock + firmware install... (either 4.1 or 4.2.1 whichever is best and easiest in the market )


    Should I install 4.1 I have 4.1 SHSH saved..
