First of all I would like to clarify some things about jailbreaking your iPhone. Apple never intended for you to customize your iPhone, and therefore jailbreaking it will violate your warranty. But if you should deside to jailbreak your phone and something goes wrong, remember to keep an updated restore point in iTunes, and you will easily restore your phone to its originally settings. Then you can use your warranty for whatever reason, and Apple will never know.
There are several reasons to why you should jailbreak your iPhone. Here are some ideas as to why:
- Intalling 3rd party applications
- Full customization of your phone
- Unlock for all mobile carriers
- Video recording (comes with the new 3gs)
- Change how your iPhone interface looks
Examples:
Lets go to the process of jailbreaking your phone:
Step 1
Download redsnow for Windows
here .
Redsnow uses restorepoints according to your phone and OS. Pick your phone and os from the list and download your restore point: (right click --> save as)
After you've found your phone and os, install redsnow. You should see an image like this.
Redsnow will ask for your restorepoint, click browse and locate your point of restore (named *.ipsw)
After you have found and verified your ipsw file, redsnow will ask you to install either Cydia or Icy or both. Pick one of them and continue. Personally I would chose Cydia and not Icy. Icy has been known to cause problem with os 3.0.
Step 2
Turn your iPhone off, and connect it with your USB cable to your PC. This Picture will appear.
Once you click next, be ready with your fingers on the power and home button.
The sequence goes like this:
1 Hold your power button for 3 seconds
2 While holding the power button, press your hone button and hold both for 10 seconds.
3 Release your power button and continue to hold your home button until redsnow detects your phone.
Your phone is now in DFU mode, and will restart and jailbreak it. This took about 15 min for me to complete. Please be patient, and when it's done you have a jailbroken iPhone with Cydia or Icy.
Enjoy!
