Ac1dsn0w will work with iOS 5 and 5.0.1 on iPhone 3GS,4, iPod Touch 4G, and iPad 1. Ac1dsn0w provides tethered jailbreak and the software based jailbreak tool comes with a tethered boot utility. It has Pwned DFU mode and Exit Recovery mode apart from jailbreak option.
Jailbreaking using Ac1dsn0w
If you have already used jailbreak tools for your iPhone to jailbreak the device and remove software restrictions, you won’t find anything amusing or different in Aci1dsn0w. You can use this software to jailbreak your iPhone in tethered mode. If you have already jailbroken your iPhone, then there is nothing new for you available with Ac1dsn0w. iPhone users who don’t have a jailbreak on the device can go with Ac1dsn0w as it is the newest in the group.
