Baseband hack

Users relying on software carrier unlock ultrasn0w must use sn0wbreeze created custom IPSW firmware to upgrade there iDevice to an upgraded iOS version without updating the baseband which breaks the unlock. However, Apple iTunes prevents users from upgrading or restoring to these custom IPSW files and errors out the process with codes and - for which we have shared solution earlier.

Here is an step-by-step guide to restore an custom IPSW file to iPhone using iTunes the correct way without any errors. If you are one of the unlucky few who rely on an carrier-unlock for iPhone 3G and accidentally updated to iOS 4.

In this comprehensive step-by-step illustrated guide we will walk-trough the complete process of jail-breaking and unlocking an iPhone 3G running iOS 4. As one might expect, the The signal is still at the correct frequency, but the devices can no longer understand each other. Now it was time for another of those basic questions. What would happen if you did the same thing to a second ESP?

So what can you do with this? If your thing is devices being forced into operations they were never intended to by particularly twisted hackers, check out our recent coverage of the USB serial adapter turned SDR by [Ted Yapo].

The New York Times reported on research done by [Charlie Miller], who also helped find one of the first iPhone bugs, so we think the report is fairly credible. The would-be hacker creates a fake cell phone tower to get the targeted phone to connect with it, at which point the fake tower would be able to transmit the bad code. Moreover, that code must be capable of running on the firmware, representing another level of hacker know-how necessary to run the trick.

A new open source software called OpenBTS allows pretty much anybody to set up a cellular network radio tower. Back in the day, it would take tens of thousands of dollars to accomplish the same feat, making this sort of hacking basically impossible for the average hacker. This kind of hacking is also illegal, as intercepting phone calls over licensed frequencies is against federal law. Weinmann will unveil his hack at next month's Black Hat information security conference in Washington DC.
