The new BootROM, known as iBoot-359.32, has proven challenging for hackers, who have only been able to implement the tethered jailbreak, which requires users to connect their iPhone to a computer via USB every time they reboot the device. Hotz claims his latest hack will not require a USB connection.

While iPhone users can rely on jailbreaking to unlock their handset for use with unauthorized carriers, the 3G-capable version of the iPad, scheduled to arrive in late April, ships unlocked by default. However, its 3G frequencies are only compatible with AT&T in the U.S.
