    Default Is My 3GS Jailbreakable?

    Hey

    I recently bought a 3GS on Vodafone (mid January). Everything is a lot different than I remember Jailbreaking wise compared to the days of FW 1.1.2 and the like, and I wondered whether my 3GS is Jailbreakble (even if tethered)?

    It's a 32GB 3GS, with pre-installed 3.1.2. I don't know about the baseband/bootrom (or even what they are as I only used to Jailbreak Touch's). And the serial number starts with 88951.

    So in a nutshell, is it do-able? And would I be able to restore to plain 3.1.2 after JB'ing if I wanted to?

    Thanks.

    It is week 51 so it is most likely a new bootrom.

    This means a tethered jailbreak is possible.

    You have not backed up your 3.1.2 SHSH via either cydia or the firmware umbrella. This means it is not possible to revert back to unjailbroken 3.1.2. You would need to restore to 3.1.3 to remove the tethered jailbreak

    Thanks for the information.

    Isn't there some controversy around upgrading to 3.1.3 as it makes it almost impossible to re-jailbreak it? (At the moment)

    Edit: Also, for jailbreaking, do I restore to 3.1.2, then run blackra1n? Then restore backup of settings and content in iTunes?

    In your case, yes it is impossible to re-jailbreak once you have restored to 3.1.3, however it is the only way to remove the tethered jailbreak on your iPhone. Keep this in mind when deciding if you want to jailbreak.

    Stay away from blackra1n for jailbreak!!!! It is not recommended.

    You can't restore to 3.1.2 EVER, (well at least until an untethered jailbreak is available for your bootrom)

    Your choice are redsn0w 0.9.2 or blackra1n, I would recommend reds0w (much better jailbreak) but to use blackra1n to kickstart the boot process after you have actually jailbroken with redsn0w.

    This gives you the superior jailbreak (redsn0w) and the faster kickstart (blackra1n)

    Okay I'm looking into redsn0w. I only really want to Jailbreak and not unlock for psx4iphone to run some of my nostalgic games. Got a few more questions just to be safe, as I'm much more wary of my 3GS compared to my 1st Gen iPod Touch.

    1. While in a tethered jailbreak is performance less stable? Or the same? Because I don't really want to have to boot from my computer too often.

    2. If anything goes wrong is my fail-safe to restore to 3.1.3? Would that in effect wipe it clean of anything related to the jailbreak?

    3. This is probably a daft question, but this wouldn't interfere with my contract in any way?

    The jailbreak by itself does not make your system any less stable

    It is what you install on your jailbroken phone that impacts stability. Stay away from stuff that hooks in at system level and is always loaded.

    That said most popular items (like sbsettings for example) are quite stable.

    No, but apple can refuse to repair/replace the phone under warranty if they see it is jailbroken. However restoring to apple ipsw (eg 3.1.3) will remove all traces of jabreak

    Buddy the performance would be the same . the only difference would be the booting method. And jailbreakikng never conflicts with the contract. But again do it on your own risk.

    I hope i am not wrong olethros bro :-)

    Thanks for all the responses. Would psx4iphone possibly be too labour intensive and cause it to reboot?

    In case I was not clear before. Ordinary apps like an emulator are fine on a jailbroken phone. This is something Apple won't allow in the app store because of legal worries.

    Where most people experience problems is when they start installing stuff from cydia that modifies the system (themes, changes to built in apps, patches to bypass limits set by Apple). These types of programs take advantage of the fact that they Have full access to the iPhone OS and can do things that would be impossible from an AppStore app.
