I Pwned, jailbroke and activated my iPhone to bypass the iTunes activation. I've been able to use my regular AT&T SIM card from my older account so that I don't have to pay for the unlimited data plan and I haven't had any problems with it working. I also discovered later that the phone appears to be unlocked to a tmobile prepay SIM card.

The thing is that I KNOW I didn't install any bootloader files or enable the baseband update to install bootneuter to allow you to unlock the phone when I built the custom firmware to flash the iPhone.

So has anyone come across this situation?

I'm just trying to figure out why the phone appears to be unlocked to a tmobile prepaid sim card.

Is it a hand-me-down phone, or bought used?

If so, there is your answer as maybe previous owner unlocked the phone to all SIM cards, not just a T-Mobile one.

Nope. It was a new out-of-the-box iPhone. I checked and I noticed I used iPwnage Tool 1.0

Only the activation button was checked when I built the custom firmware.

Just to clarify, the phone is 1.1.4 OOTB.

Also, I forgot to mention that the phone was previously jailbroken and activated with ZiPhone (I'm not sure which version, but one of the first or second versions) for the 1.1.2 firmware. Later I jailbroke and activated on 1.1.4 using the PwnageTool.

I just read the "ZiPhone warning." Could someone remind me how I can check to see which bootloader version I'm running?

If I remember correctly, a 1.1.2 OOTB iPhone came with the 4.6 bootloader. Also, if what I'm reading from the above "warning" is correct, then maybe my iPhone's bootloader was inadvertently downgraded then the phone was unlocked by ZiPhone when all I tried to do was jailbreak and activate the phone.

Could anyone confirm this logic with me?

Thanks for your time and help.

if your phone is currently running 1.1.4. You can add http://installer.iclarified.com to your source. Install bootneuter. When you run bootneuter, it will tell you exactly what you have. Don't hit the flash button.
The screen looks like here: http://wikee.iphwn.org/sgold_bootrom:bootneuter
Item in "blue" is currently what is on the phone.

as for ur original question your phone is unlocked coz pwnage (atleast winpwn for windows) runs bootneuter when the phone is first booted after pwning so mayb thats why your phone is unlocked

to check what boot loader version u have without wanting to tamer with it install BBinfo (baseband info) or HWinfo (hardware info)
if u wanna upgrade or downgrade BL use bootneuter

BBinfo will give you the bootloader version but it will not tell you if it is FB (fakeblank) or not.
Since it was ziphoned, it's best to find out exactly what the bootloader is. If it is 3.9 and fb=off, then you know the phone was downgraded 4.6 to 3.9 by ziphone.

HWInfo (by trejan) displays the baseband bootloader version as 3.9_M3S2 on the above mentioned iPhone, which by the way is a week 46 iPhone.

This is the same bootloader version as on an older iPhone of mine (week 30) which has a legitimate iPhone AT&T plan and I activate through iTunes. I've only used ZiPhone to jailbreak this phone when I was updating to 1.1.2 and 1.1.3. I'd then activate through iTunes. Some time later I used PwnageTool to jailbreak it so I could update it to 1.1.4. I got this older week 30 phone back in September 2007 when they still were selling iPhones with 1.0.2 firmware and, I assume, the older 3.9 bootloader.

Under normal circumstances, I assume the bootloader never got upgraded during any of the past firmware upgrades. Is this true?

- week 30 phone. Definitely 3.9 bootloader regardless if you use ziphone or not.

- week 46 phone. Default is a 4.6 bootloader. If you used ziphone ONLY to jailbreak+act (ziphone -a -j) then bootloader is not touched. Like you said, you never unlock it, you used pwnage but did not choose the bootneuter part and etc ... How you have 3.9 BL is beyond me. Something must have unlocked it therefore your t-mobile is working. How ??. Now back to what I was saying, if you have 1.1.4 on the phone now, you can simply run bootneuter without it doing anything to the BL or BB (as long as you don't hit flash), we will know and at least guess at what was done.

- Firmware upgrade never change the bootloader.

- One exception, if your BL is 3.9FB, downgrading to 1.0.0 or 1.1.1 fw will give you a 3.8 BL.
