    Default not stuck at reboot screen, but iPhone doesn't reboot so no jailbreak

    I successfully restored a previously pwned and unlocked iPhone 2G to version 3.1.3 of the firmware, with an AT&T sim inserted (effectively upgrading the OS from version 3.0.1). However, I'm unable to successfully jailbreak said iPhone. I've tried redsn0w 0.9.2 to no avail:

    I left all the options except "already pwned" unchecked (I don't want Cydia). The kernel and ramdisk get uploaded to the iPhone, but the iPhone doesn't actually reboot and is stuck at the black (backlit) screen. Disconnecting and reconnecting the USB cable does nothing. When I forced a reboot by holding down the home and power buttons, I was back to where I started before running redsn0w -- i.e. the "illegal SIM - connect to iTunes". I ran redsn0w again, and the same thing happened!

    Any ideas as to how to fix this problem??

    The solution was to uncheck "already pwned," which put the iPhone in DFU mode -- but that wiped out my proper activation!

    You lose the existing pwn by restoring or upgrading with a stock Apple IPSW.

    Also, why don't you want Cydia? There is little point in jailbreaking without an ability to install jailbroken apps. I hope you aren't planning on using Rock.app (which has been proven to be unreliable)

    You should not have been hacktivated if you had an AT&T sim inserted. I would try again.

    Thanks. I should have realized that.

    I have to jailbreak in order to use a sim from a carrier other than the one to which the phone is locked, don't I? Even if the baseband is permanently unlocked, I don't seem to be able to use the phone with a stock Apple IPSW.

    Thanks. I must have inserted the wrong sim -- it was late at night and I had panicked.

    I hate iClarified -- their tutorials are vastly oversimplified and often inaccurate.

    Yes you are correct. You need hacktivation. In this case you need to perform the jailbreak with the SIM from another carrier inserted.

    This wipes your proper activation. You can activate legitimately - export the push/youtube certs - then jailbreak/hacktivate and import in the push/youtube certs. Or you can use pushdoctor.

    Wait a second. With my ATT sim inserted, restoring to stock apple firmware and then running redsn0w 0.9.2 should keep activation and allow me to use a T-Mobile sim, right? (By the necessity of jailbreaking, I meant that I can't restore to stock apple firmware and use my t-mobile sim, even though the baseband is already unlocked.)

    If not, then I should just build a custom firmware with pwnagetool -- but for some reason, that fails every time. Why?

    Nope - redsn0w either detects an AT&T SIM - normal activation or detects another carrier's SIM - thus hacktivation.

    So if you want to use multiple carriers - you need to jailbreak with the non AT&T sim card.

    Similar behaviour with PwnageTool (but you can determine whether you use hacktivation or not via a button)

    Are we having a misunderstanding?

    This isn't what I have observed: in other words, once an iPhone is activated and jailbroken and unlocked, it will work with *any* sim -- the difference is between hactivation (push notifications broken) and activation (proper certificates)

    For example, when I purchased my iPhone 3G from someone, he had already activated it with his AT&T sim. I applied redsn0w using my own AT&T sim (without active account), and the activation was maintained; installed ultrasn0w via Cydia, and then I could use a T-Mobile SIM. Push notifications work.

    Recently, I used PwnageTool to create a custom 3.1.3 firmware without activation for the same iPhone 3G. I restored with the AT&T sim installed; the iPhone was activated, and jailbroken, and once installed ultrasn0w, it worked with a T-Mobile sim.

    If redsn0w and PwnageTool are similar, then with my previously-unlocked iPhone 2G, I expect that once I activate and jailbreak using redsn0w with the AT&T sim inserted, I will both preserve activation *and* be able to use a T-Mobile SIM.

    You are welcome to try this out - my understanding is that 3G/3GS and 2G work differently with regards to whether swapping SIM cards triggers activation.

    You are right, but what I'm talking about is: after jailbreaking, once activation is successful, then one can use a different sim card, regardless of whether it was a "real" activation or a hactivation. I don't think that this depends on the model of iPhone, does it?

    It turns out that the AT&T sim card that I have does trigger a proper activation on my iPhone 2G, so that I would expect that after running redsn0w with that same sim card inserted, I should then be able to insert my T-Mobile sim and use my phone.
