Lets get started with a step by step guide (It will be a short one this time around!)

1) Update your iPhone 3G to 3.0 . You have two options here :

2) Now that you performed the Jailbreak steps necessary in Step 1, all you have to do is pop in your SIM card(be it T-Mobile or any other GSM carrier).

  • Turn WiFi ‘On’ on your iPhone 3G and connect to a Wireless Access point (WiFi). (Create an AdHoc WiFi Access point if there is no WiFi access)
  • Disable 3G on your iPhone if you are on an unsupported frequency (T-Mobile). Other carriers, try disabling and then enable once unlocked!

  • Launch Cydia on your iPhone 3G and download the necessary upgrades if prompted and hit ‘Restart Springboard’ when done.

  • Once it refreshes, return to Cydia and hit the ‘Done’ button and tap the top most entry shown.
  • Now tap Ultrasn0w -> choose the install button and Confirm. Now return to the main menu in Cydia.

    Hey there just wanted to give you a brief heads up and let you know a few of the pictures aren’t loading correctly. I’m not sure why but I think its a linking issue. I’ve tried it in two different web browsers and both show the same outcome.

    AMAZING! Thank you so much, I've been trying for days to fix my iPhone!!!! 😀
    At first, a bunch of windows popped up on the screen, but just kept pressing "okay" and then, the signal started to read "searching" and voila!
