Apple sends iPhone Hackers back to the Drawing Board

“It’s a cat-and-mouse game,” said Steve Jobs. “We try to stay ahead. People will try to break in, and it’s our job to stop them breaking in.” The cat has caught the mouse, for now.

In a serious setback for the capability to install third-party native applications on the iPhone, as well as activate the device without an AT&T SIM card, Apple has changed the encryption methodology for the iPhone with the 1.1.1 firmware/software update, meaning that old processes for “jailbreaking” the device — putting it into a mode where files can be written to and from the phone — are now defunct.

The new encryption method is apparently similar to that used by the iPod touch, which hackers have thus far had little success in jailbreaking.

Apple’s change is also bad news for tools that make modifications without requiring jailbreaks, like Ambrosia Software’s iToner, designed to add ringtones to the device without going through iTunes. Ringtones placed on the iPhone by that application did not survive the update to firmware/software version 1.1, and new ringtones cannot be transferred to devices that have been updated.
