Change MAC-Address in iOS5

Question

I Used to change my Mac Adress in Open Networks with the command:

ifconfig eth0 ether 00:11:22:33:44:55

in iOS4 this was no Problem, i remember there was even an App on Cydia for that. For ifconfig i instaklled network-tools from BigBoss Source.

Since iOS5 the Command is going thru Terminal without any error, however the MAC-Address isnt changing anymore... Someone a Idea on how to change it?

Solution 1

It's possible. For some reason, spoofing it in iOS 5 won't work (either via command line or MacX4), but you could always rewrite it in hardware. There are several cons to this and this is not worth during unless you absolutely have to: it will break your music player (so you have to use VLC or the like), is permanent even after reboot, and effectively changes your UDID (so betas will not work and the device will be unregistered).

nvram wifiaddr="XX:XX:XX:XX:XX"

Again, the cons definitely outweigh the pros here. I'm sure eventually someone will come up with the software to do a spoof, not a total rewrite.

It can be done. My iPad running 5.01 has an arbitrary MAC. There are no restrictions as far as playing music, and I am still able to access Apple services (at least those that I use personally) without hindrance. It's a moderately tedious process, but after a bunch of failed attempts I was able to successfully (and permanently unless I decide to repeat the process using my originals) change the values with a combination of terminal commands, DFU/recovery cycles, OSX apps, and a clean restore via iTunes. If anyone is still interested, I would be willing to outline the process. I would do so now, but I have to hash out some specifics concerning the iTunes host file.
