  As each phone has its own serial number which is registered, you should maybe try to return it to the owner first. That being said, it depends on what model the phone is. But you could try putting the phone in DFU mode, connect to iTunes and then restore to factory settings. If phone has authorized carrier sim card, then update to latest OS using iTunes; if not, update with custom OS and then jailbreak and unlock it.

  Why not update to latest firmware 3.1.2:
  Use custom firmware to jailbreak:

Thank you. The Jailbreak worked fine. The Unlock is the problem. It says “different sim detected. Please connect to itunes”. I can’t access the apps, messages, phonebook, etc. & all my calls are emergency calls. Please help me!! Did I do something wrong or do I need a new program??

        Leave the sim card in the phone when going through this process. Do not update the phone using the iTunes version of the OS. Use the custom OS instead, which you will install on your phone by holding down the shift button on your computer while clicking update and install in iTunes. Then follow all the other steps in this tutorial.

Im stuck on the waiting for reboot menu what do i do

This worked perfectly for me. I have an iPhone 2g which was previously jailbroken and unlocked to 2.2.1 OS. Started experiencing shutdown problems after updating some of my apps through iTunes. Realized those updates were meant for phones that were updated to 3.0 OS. Used the custom 3.0 OS and then proceeded to jailbreak. I did note that when I added a 3rd party app through Cydia that phone started to shutdown again. Deleted the Cydia app and phone is no longer shutting down. Be careful of adding third party apps if you update to 3.0 OS. Convinced that certain 3rd party apps do not play well with the 3.0 OS.

Wow, thanks so much for a clear and easy-to-follow tutorial (and to all the users who posted helpful hints & tips). I’m now in business using my iPhone 2G 3.0.1 with T-mobile (no data plan) and wi-fi.

I did all steps exactly as it said, and when it started rebooting, the screen on the iphone changed to “downloading jailbreaking data” and then the phone got locked again and I already repeated the process two times and it happens again what can I do?

I was able to go throught the entire process and was able to unlock and jailbreak my iphone. I have one problem though I connect to a wifi network but when I try to open an app that requires wifi (Cydia for example) I get an error unable to load, or Youtube which says not able to join at this time. I have full bars on wifi connection when I did this. Please can someone help…
