Trying to unlock an iPhone 3G for use on other networks…

A friend happened to purchase a iPhone 3G for a decent price, and was wanting to know if it could be used on other carriers networks.  I have jailbroke an iPhone 3GS but never needed to unlock it. (I just use it for pandora) Sources this seemed possible to acheive….little did I know that unlocking is a bit more difficult.  There are programs to help you acheive the jailbreaking/unlocking tasks. 

  • Redsnow – used to unlock and jailbrake an iPhone.
  • tinyUmbrella – used to show info about an iphone even if iTunes cant.

Using redsn0w I checked the box that said install Cydia.  I then had to place the phone into DFU mode by:

  1. Press and hold the POWER and HOME button togeter for 10 seconds.
  2. Release the POWER button while still pressing the HOME button.
  3. After 15 seconds release the HOME button.

The phone should now be in DFU mode. redsnow should then continue jailbreaking the device.  After that process is complete, I ran redsnow again with the “install iPad Baseband” box checked. 

Once the phone rebooted, u had to install snowbreeze on the phone to enable the iPad baseband. One more reboot and 20 minutes later, the iPhone was working on tmobile’s family network.
