Apple released iOS 4.3.5 for iPhone, iPad and iPod touch. After some time, MuscleNerd, the leading member of the iPhone Dev Team, has also confirmed that iOS 4.3.5 jailbreak is possible. However it would be a tethered jailbreak, meaning that every time you want to reboot your iPhone, iPod Touch or iPad, you have to plug it in to the computer and do the jailbreaking process again in order to use your device. If you do not do so, then it will just get stuck on the Apple logo and won't boot up until and unless you boot tethered using a computer and the very same redsn0w software you used to jailbreak it. The files required for jailbreak are also important for boot tethered, so keep them safe, the following files you are required to download:
- iOS 4.3.5 for iPhone, iPad and iPod touch- iOS 4.3.4 for iPhone, iPad and iPod touch- Redsn0w 0.9.8b4 for Windows and Mac- iTunes 10.4 for Windows and Mac
Also keep in mind that iPad 2 is not supported for this jailbreak.
