How to unlock an iphone 3 g

  1. 1. HOW TO UNLOCK AN IPHONE 3G/3GS To be used withTmobile or other GSM networks.
  2. 2. Pondering  Have you ever been frustrated with the desire to obtain an iphone but simply cannot use one because you do not have service provided by AT&T. My friends you are troubled no more. I am here to show you a way to use your iphone onTmobile or any other GSM network that is available. All you need is a sim card and the ability to follow along as these instructions guide you. Its very simple!
  3. 3. Understanding…  Iphones are initially manufactured to be used with AT&T and are set so that inserting another sim card will result in the phone reading “Invalid Sim Card”. However, given the following method, most phones will be able to operate underTmobile.There are a few ways, but I will show you the way most simple.
  4. 4. Jailbreak  The first step to unlocking an iphone would be to jailbreak it. It is important that you know more or less what jailbreaking is. Jailbreaking is a way to run applications and use themes that have been approved by apple. Many of them are free.
  5. 5. How To Jailbreak  Jailbreaking your iphone is a very easy process.You must start out with an AT&T sim card. Once you are on your iphone, simply visit the site www.jailbreakme.com on your iphone.Once you are on the site you simply slide the bar across and the jailbreaking process will begin.  As displayed in the picture, all you have To do is slide to jailbreak. Simple as that!
  6. 6. Once Jailbroken  Once you have jailbroken your device, it is time to get a little technical. After an iphone is jailbroken, an application entitled “Cydia” will be installed on your device. Open Cydia and go to the tab at the bottom that reads “Sources”  The brown tab first in the fourth row is cydia, Once that is installed the rest is pretty easy. After Cydia is opened and the “Sources” tab is clicked Simply go to the red cross at the top that reads “Add Source”.Type in http://repo666.ultrasn0w.com
  7. 7. Ultrasn0w  Ultrasn0w is the unlocking application that allows for other sim cards to be used on this iphone.Once http://repo666.ultrasn0w.com is installed on the phone, the phone will reboot. After the phone reboots go into the iphone’s settings. Search for “Network” and turn OFF 3G. (Tmobile does not use a 3G network so it is not necessary). After the 3G option is switched to off it is safe to insert your sim card. Once the sim card is inserted the phones network that originally read “AT&T” will now read “Searching”; this is good as it means you are doing the following instructions correctly.
  8. 8. Accessing your carrier  It is important that once you insert your sim card from another carrier, that you reboot the phone. (turn off and back on again) Once you do this the network should still read “Searching”, wait a minute or two and the carrier that you are comfortable with will now be the powerhouse of your iphone.
  9. 9. Enjoy  Now your iphone is unlocked/jailbroken.You haveTmobile or a similar GSM network and you have the luxery of accessing hundreds of applications and themes for your phone. Enjoy and browse.The fun in it is that you now have an apple device with the freedom to do what you want with it. 
  10. 10. Disclaimers There are some instances where an iphone cannot be unlocked… This process will only work on an iphone 3G/3GS whose modem firmware is not exceeding an IOS of 4.0 and the baseband of 5.12.02. If you are past this firmware, you are still in luck.There was recently an application leaked on the internet that will now unlock any device. Go to the internet on your phone and visit www.greenpois0n.com.That should do the trick!! Also…I am not responsible for anything that may go wrong while trying to conduct this operation, this is simply advice and a helping hand.
