    Default 3GS, old bootrom, eternal jailbreak possible?

    hi

    when i finally upgraded an old iphone2G last weekend to 312 and used redsn0w to jailbreak, i noticed that in the redsn0w instruction, it is stated that both iphone2 and iphone3G are essentially hacked forever and any new fw can be jailbroken (or jailbreak implemented) due to bootrom exploit.

    for the iphone3GS it states that jailbreak works becasue of usb exploit that will most likely be patched in next fw release.

    what does this mean for iphone3GS with the old bootrom? as far as i understand, the bootrom exploit in the old bootrom is essential for an untethered jailbreak. so we are covered here. and someone mentioned of devteam mentioned jailbroken once equals jailbroken forever.

    but will -once a jailbreak for new firmware is found- the application of the jailbreak be more complicated or do we "simply" switch to pwnage tool to create custom firmware and then with the "magic" of our saved ecid numbers/sigs/saurikscydiarepository we can circumvent the apple firmware check and be happy?

    is there any answer possible yet or do we have to wait and see how jailbreaks continue with iphone 3GS, be it the old or the new bootrom?

    In short, yes. As long a you have an ECID SHSH for 3.1.2 (even better 3.0) and the old bootrom you can remain jailbroken forever.

    The chances are much higher that OS 3.2 and eventually 4.0 will be jailbroken via pwnagetool than a direct jailbreak (like redsn0w or blackra1n)

    The logic behind this, is that the devteam may choose to keep new iBoot exploits private and purely release a jailbreak to those already jailbroken via pwnagetool. This allows them to not burn up valuable iBoot exploits that Apple simply closes with the next OS release.

    Just to be 100% clear. Upgrading may remove your ability to software unlock. If you have 3.1.2 ECID then jailbreak is for life. Unlock you need to be careful with any upgrades as you can't downgrade baseband.
