iPhone’s radio rom has been extracted, and the tool to do it has been made public so that everyone can join the effort:
DOWNLOAD: http://www.deadbeef.cn/NORDumper.tar.bz2
To run this, copy it to /usr/bin and set the executable flag with chmod.
add Disabled to /System/Library/LaunchDaemons/com.apple.CommCenter.plist and reboot.
run: NORDumper dump.bin
Now, if you notice, Apple isn’t caring too much about this, they’re more agressive on iPhone emulation than iPhone hacking, guess you can’t hack without owning one =)
