Hi Gurus

Recent collected sets from Maxis cannot be jailbroken. (3sets fresh from seal packing)

After normal sim activation.

Ran Blackra1n
nice pic of geohot

reboot into restore mode

tried also custom_restore (Pwng)

still same.

any ideas?

thx
please dont flame me for new thread

is it possible to JB the new iphones already??
mine is week 44...
or the only way is to tethered JB

sadly, no. the most accurate way of determining is your set can only be JB via tethered JB is checking its bootroom version rather than manufacturing week as even some with later manufacturing week is able to run via normal JB.

Just gotten myself an iPhone (iPhone 3GS 16GB - SingTel) but I am not sure whether it is fine to jailbreak it or not. I was planning to try out blackrain but my mates told me that there are a higher than normal chance of bricking it... Is this true?

How to check the bootroom ahh bro??
sorry..

iPhone has almost zero chance of bricking TBH.
do a search via the 'Search' button. the topic has been discussed numerous times.

Thanks for the reply - just one more question - must I determine the bootrom number before using blackrain? As I just got my iPhone yesterday, I am wondering my iPhone is one of those newer versions that will hit problem like everytime I reboot my iPhone (after blackrain), it will go into DFU mode automatically?

Don't really understand what it means that I must use blackrain everytime I need to reboot - does it mean that I use blackrain to reboot, or I need to restore my iPhone after reboot and then blackrain it again?

How to check your iPhone's bootrom using Windows:

Put your iPhone into DFU mode (how to/tutorial for this step at iClarified).

Then go to Start -> Control Panel -> System -> Hardware -> Device Manager on your Windows machine.

Look for 'Universal Serial Bus (USB) Controller', you will find 'Apple Mobile Device USB Driver' as a subitem there.

Right Click and choose 'Properties', navigate to 'Details' tab and select Device Instance Path from the dropdown list box. At the end of this information string you will find the bootrom version, e.g. [iBoot-359.x].

What does tethered mean?
A tethered jailbreak is one where in order for the iPhone to boot up, it needs to be connected to a computer with special software (blackra1n), or it won't turn on / will turn on unjailbroken (depending on the implementation)

When the iPhone (or iPod touch) boots up, it checks the firmware to make sure it hasn't been modified. Untethered jailbreaks make the iPhone skip this step, allowing it to boot jailbroken firmware. Tethered jailbreaks need an external device, usually a computer, to insert a command so the iPhone can boot jailbroken firmware. So the jailbreak is never erased or "forgotten," just the ability to run it.

for iPhones with new bootrom, the jailbreaking process is the same.

the only thing to take note of for your unit is, everytime you power off/reboot your unit, you will need to connect it to your PC and run blackra1n to rejailbreak. that's what tethered jailbreaking means.

Thank God that you ain't in front of me now else I would have given you a bear hug for the prompt and perfect reply that I have been looking for. Thanks a lot mate for the explanation (and not simply directing me to the search function)

Just one LAST question, is it possible to start up the iPhone (from DFU) without re-jailbreak?

is there anyway to let OS 3.1.2 become untethered? Looking the solution on it.
Heard that there is no way to do the untethered the phone in the mean time.

Availablity for windows came out long time ago

for windows, only blackrain is available. For pwnagetool it is still mac only. I am still waiting for pwnagetool to be available for windows for 3.1.2.

You still can jailbreak for OS3.1.2. It's only those phones with the latest bootrom that you can only do so with a tethered jailbreak.

And at this point in time, there is no solution yet for a full jailbreak.
