iOS 4 / 4.0.1 Jailbreak & Unlock for iPhone 3g

How to Jailbreak and Unlock the iPhone 3g for non-AT&T sim users (T-Mobile, etc).

  1. Update iPhone 3g in iTunes 9.2 to the current 4.0.1 firmware.
  2. Download Redsnow 0.9.5 for Windows or Redsnow 0.9.5 for MAC. This is used to Jailbreak.
  3. Download iOS4 for iPhone 3g. Redsnow will need this file.
  4. Turn the phone off by holding the power button. Open RedSnow 0.9.5 and follow the instructions.
  5. When complete, turn the WiFi on in the iPhone.
  6. Open Cydia and let it update itself.
  7. Add the REPO ''
  8. Find and run Ultrasnow in Cydia and you are done!

I hope this has helped you as it worked great for me yesterday! Let me know if it works for you. Thank you!

  1. Thanks for the steps. Both jailbreak and unlock worked of me. However, I found that my iPhone 3G (ios 4.0.1) seems to run a litle slowly. Did I do something wrong? Is there a way to fix that?
