I have an iPhone 3GS which is on iOS 6.1 baseband 5.16.. new BR. It is a carrier locked phone, so am unable to go past the activation screen. What can i do now to unlock and jailbreak it?


Part 1: Determine Eligibility

  1. Find your serial number (Settings -> General -> About -> Serial number)
  2. Go to this website
  3. Carefully enter your serial number
  4. Click 'Laat de informatie zien' (Show the information)
  5. Look at the lines "Production year:" and "Production week:"
  6. Compare your numbers to the information below

Production year is 2009 or 2010: You have an eligible device. You may proceed to Part 2.

Production year is 2011: Look closely at the production week. If your production week is 33 or lower, you have an eligible device. You may proceed to Part 2. If your production week is 34 or higher, STOP! Do not proceed to part 2, your device is not eligible.

Production year is 2012 or 2013: STOP! Do not proceed to part 2, your device is not eligible.

WARNING: Do not proceed unless your device is eligible! Doing so will brick your device! If you have any question as to the eligibility of your device, join our IRC channel at irc.freenode.net #jailbreakQA and ask if your device is eligible.

Part 2: Download Required Files

  1. Get redsn0w for windows or mac

  7. Click Back
  8. Click Jailbreak
  9. Select "Install iPad baseband" and "Install Cydia"
  10. When asked if you are sure you want to proceed, click 'yes'
  11. Follow the DFU instructions
  12. When that completes, close redsn0w

Part 6: Unlock and Untether

  1. Open cydia and let it complete loading

  3. Tap 'Refresh' in the top-left corner
  4. Wait for cydia to finish loading. If you get an error, tap refresh again.
  5. Tap search, find and install 'evasi0n 6.0-6.1 Untether' and 'ultrasn0w' (those are zeroes, not capital o's)
  6. Reboot iPhone (power off/on if it doesn't reboot automatically)

I cannot go pas the first step Find your serial number (Settings -> General -> About -> Serial number)

Download redsn0w for your operating system (the links are in part 2). Open redsn0w with your device connected, and go to extras > even more > identify. Look for your serial number in the box that opens up.

Well i used Snowbreeze 2.9.9 and got my iPhone 3gs untether jailbroken on 6.1. But now how do i unlock it? I have no service. Btw my phone seems to be a new model as the production week is 37 and year 2011. Plus my baseband is at 5.16.08. How should i proceed?

If your production week is 37, you cannot unlock using the baseband upgrade / downgrade method I posted above. There's no way for you to use software to unlock. You need to buy a cheap IMEI unlock from a site such as this or this.

And there is no story about the baseband ? Whatever the baseband that I have, it will work if my phone was manufactured at the correct date ? I thought the part 4 could work only with some baseband ... ?

When you install iPad bb on eligible iPhone it is 6.15.xx. When you downgrade the hack installs bb 5.13.xx, which is the highest Ultrasn0w is capable of unlocking for 3G and 3GS.

Prior to trying anything you will want to correctly identify your device, that means the model (eg MC135B), version (6.1) serial (first five digits), imei (keep to your self for now) and baseband (5.16). Do not attempt to run redsn0w or unlock tutorials on this until you know it's safe as error is fatal.

When i connect my iphone to the PC and start Redsn0w it says iPhone (6.1, new BR, 05.16.08), So i guess i have a new bootrom. How should i proceed now? and where can i check my model no. and IMEI as i am unable to go past the activation screen? It connects to wifi and then next step it goes to the activation screen.
