Into the Great Wide Open

iPhone hackers are making some noise because they're learning to fly. It's almost too good to be true.



Buy It

Try It

London (IDG) -- Third party applications can now be installed on the iPhone. There are now at least three ways to bypass essential security measures in the device.

Installer.app

Installer.app is a UIKit based package manager for the iPhone. It works by downloading packages over WiFi or EDGE. It supports installing, updating, and uninstalling applications.

Also available is a single command installer for Installer.app which automates the entire jailbreak and Installer.app installation process.

The Installer.app page also includes documentation for creating application packages for the iPhone.

iPHUC

The iPhone Utility Client (iPHUC) is the followup to the earlier iPhoneInterface which allows command line access to the iPhone from an external computer. It is maintained on Google Code.

Turbo SIM

The Turbo SIM hack - a combination of a blank Turbo SIM card together with AppleSaft from Bladox - makes it possible to enable all but EDGE support without the customary (expensive) AT&T activation - and it also makes it possible to use the Apple device on any GSM network with full incoming and outgoing telephony services. Further instructions can be found here.

/*
 * iPhone baseband SIM lock 0wnage PoC
 *
 * History:
 * 0.92 - User Interface, ICCID/IMSI are read from a card and
      then used with another
 * 0.91 - some fixes, PROC_8_CONFIG_INIT_BOOSTER for speedy init of ICCID file,
 *      needs bladox turbo kernel >=1.2.7
 * 0.9 - original version
 *
 * Compile, load on your leet Bladox gear
 * disable your subscription PIN and enjoy :p
 *
 * Special thanks to the baseband development team
 * It wouldn't have been so easy without you :)

iPhone International?

Whilst the rumour mills are suggesting Apple will release patches to close these holes they're also suggesting Apple may be readying the release of a second explicitly 'international' device that won't require safeguards such as heretofore implemented.
