How To Update/Upgrade iPod, iPhone, iPad to iOS 5.1 using iTunes

 

This is the latest iOS release of Apple. Below are the steps to update to this latest version.









Requirements:

1. The device you want to update of course
2. iTunes (Latest Version 10.6)
3. USB Cable Connector

Steps:

1. Open iTunes.
2. Connect the device.
3. Back it up. To back up, right-click your device located at the left side of iTunes window then select Back Up. This is done to prevent the loss of your data if something goes wrong and also this back up will be used later for restoring.
4. Select your device again.
5. The Summary of your device should appear. Click Update.
6. If you have not yet downloaded the firmware (iOS 5.1), click Download and Update, if you have, click Update.
7. Wait for iTunes to do its thing (such as verify the software, back up, update then restore).

After that, you already have the latest iOS in your device. Good luck and enjoy! :)

How to Boot Tether your Device (iPod Touch, iPhone, iPad)?

This process should be done if you are on tethered jailbreak only. You must do this whenever you want to reboot your device (situations like installing Winterboard or completely losing battery) so that you can use it.

1. Make sure your device is connected to your computer.
2. Launch redsn0w (I am using redsn0w 0.9.9b6 for Windows). Select Extras then Just Boot. If you are on previous versions of redsn0w, Browse for the IPSW file > Next > Check Just Boot Tether.

 

3. Follow the on screen instructions to enter DFU mode. Wait while the process finishes up. A pineapple with a bite should appear in your device screen while the rebooting is taking place.

Good luck! :)
