With their latest redsn0w 0.9.7 RC7, iPhone Dev Team have introduced a new and simple way to boot tethered iPhone, iPad and iPod Touch. It should be a sigh of relief for users who have tethered jailbreak iOS 4.2.1.
Since you’ll need to boot tethered on each restart, it’s recommended that you create a shortcut for that so that you have to avoid running through the steps each time. This guide will help you doing just that:
How to Boot Tethered iPhone, iPad & iPod Touch
Before you Begin:
Download iOS 4.2.1 IPSW for your device (newer devices only, since older devices already have untethered jailbreak)
- Apple iPad: iPad1,1_4.2.1_8C148_Restore.ipsw
- iPhone 4: iPhone3,1_4.2.1_8C148_Restore.ipsw
- iPhone 3GS: iPhone2,1_4.2.1_8C148a_Restore.ipsw
- iPod Touch 4G: iPod4,1_4.2.1_8C148_Restore.ipsw
- iPod Touch 3G: iPod3,1_4.2.1_8C148_Restore.ipsw
Download redsn0w 0.9.7 (Windows: Redsn0w_win_0.9.6rc7b.zip | Mac: Redsn0w_mac_0.9.6rc7.zip)
Jailbreak iOS 4.2.1 using Redsn0w
Important: For ease of use, put all the files (redsn0w and iOS 4.2.1 IPSW ) at the same location
Now follow this guide:
Method 1
Step 1: Extract the downloaded redsn0w in C: drive (redsn0w.exe should be on C:)
Step 2: Place the iOS 4.2.1 IPSW on C:
Step 3: Download the one-click tethered boot shortcuts that we created. (Download Link)
Step 4: Run the relevant shortcut for your device. That’s it!
For any of these shortcuts to work, you must have iOS 4.2.1 IPSW and redsn0w.exe to be placed at C:. Id it doesn’t work, follow the method 2.
Now each time you need to boot tethered, just double-click the shortcut that you created and you’re right into it. Not the ideal solution but that’s perhaps the shortest possible way to boot tethered for now.
Method 2: Create Boot Tethered Shortcut
Step 1: Extract the downloaded redsn0w
Step 2: Right click on Desktop, select New > Shortcut
Step 3: In Create Shortcut wizard, enter:
Path-of-redsn0w.exe + -j -i + “Path-of-iOS-4.2.1-IPSW”
Examples:
- For iPhone 4: D:redsn0w.exe -j -i “D:iPhone3,1_4.2.1_8C148_Restore.ipsw”
- For iPhone 3GS: D:redsn0w.exe -j -i “D:iPhone2,1_4.2.1_8C148a_Restore.ipsw”
- For iPad: D:redsn0w.exe -j -i “D:iPad1,1_4.2.1_8C148_Restore.ipsw”
- For iPod Touch 4G: D:redsn0w.exe -j -i “D:iPod4,1_4.2.1_8C148_Restore.ipsw”
- For iPod Touch 3G: D:redsn0w.exe -j -i “D:iPod3,1_4.2.1_8C148_Restore.ipsw”
Now click “Next”.
Note: I had redsn0w .exe and iOS 4.2.1 IPSW stored in D: drive. If your files are placed elsewhere, enter the relevant path.

Step 4: Name the shortcut and click “Finish”.
Step 5: Double click the shortcut that you created to boot tethered.
