How to Unlock Your 3G iPhone

Posted by Technology Guider On January - 26 - 2009

Recently the iPhone Dev Team has created yellowsn0w and this has allowed users to unlock their Apple iPhone very easily. Once your contract is done, you’ll be able to switch it to any carrier or you can do that right now. The process to unlock your 3G iPhone is very easy. First off, make sure you have the correct Modem Firmware which is 02.28.00. To find this, go to Settings–>About and scroll down to the bottom. If it isn’t at this Baseband then go into iTunes and restore it, and update it back to 2.2. Then you’ll use QuickPwn to get it to 02.28.00. Now we are ready to unlock your iPhone.

Steps

  1. Click Cydia
  2. Click Manage
  3. Click Sources
  4. Click Edit
  5. Type in apt9.yellowsn0w.com
  6. Go back to Home screen
  7. Take your old SIM card and insert your new SIM card
  8. Power off and wait 10 seconds
  9. After waiting 10 seconds power it on
  10. On the top left, it should have the bars and your carrier
  11. If not, repeat steps 8 through 10

Now you should have any unlocked Apple iPhone ready to use with the carrier of your choice. Remember if you are using T-Mobile that you’ll need to turn off 3G.

Do you have an iPhone? If so, share your thoughts on which plan is best to couple with the iPhone as there are many different alternatives as I am totally confused on this issue.
