A talented Chronic Dev Team member known as "Pod2g" has reportedly "discovered" a bootrom-based exploit capable of jailbreaking all devices running Apple iOS 4.1 firmware - including the 4th-gen iPod touch, iPhone 4 and iPad.
According to Taimur Asad of Redmond Pie, the latest hack indicates that the next generation of jailbreaks may very well be based on bootrom-oriented exploits.
"Unlike [the relatively rudimentary] JailbreakMe, [bootrom hacks] will enable users to change boot and recovery mode logos, among many other things," explained Asad.
"[And], the best thing about a low-level bootrom exploit is that Apple won't be able to patch it simply by releasing a new firmware update."
Asad added that the latest wave of jailbroken devices could force Apple to release revised hardware versions of the iPhone, iPad and iPod.
"This is the reason why iOS devices (like iPhone 3GS - new bootrom), iPhone 4, iPad, iPod touch 3G / 4G) which shipped after November 2009 are currently not jailbreakable via PwnageTool - because it uses the 24kpwn bootrom exploit, already patched by Apple."
