TUAW Responds: MAC Addresses on the iPhone

In the "use at your own risk" department, TUAW reader Carter P. wrote in asking, "Hey, I know this is a lot to ask, but would it be possible for you to build me a simple application? All I would like the app to do is to spoof a MAC address on my iPhone." MAC addresses are Media Access Control identifiers that are used to distinguish one network adapter from another. Spoofing involves changing your hardware's MAC address from one setting to another. You can use spoofing to fix problems connecting to your ISP or to test your network firewall.

To help Carter out, I put together this iPhone/iPod touch utility. It prompts you to enter a new MAC address and then runs ifconfig en0 lladdr address. No further error checking is done so use the tool with all due caution.

Erica, can this utility be useful in case my iPhone loose its own Wi-Fi address ?; I mean, I had the "No Wi-Fi" issue as Mac address was lost; may I now insert the Mac Address manually and have the wi-fi connection back again? Thanks :)

Will we get a "REVERT" button Erica?

I've never written anything for an iPhone in my life, but my understanding is that all this app does make a nice GUI for a simple command line call. Doesn't really "modify the wireless software".

Of course if you can connect to WPA enterprise from the command line then the same thing could be done for that.

Since you did something to modify the wireless software on the iphone, think theres a chance someone could create wpa enterprise support so we could type in a username and domain, along with a network password?

So how will I be able to find out my MAC Address first so I can write it down before I change it? Modify the app so it shows the MAC it has already? Thanks Erica, I had the same question about a month ago about changing the MAC Address.

Ok, that takes care of the easy half of my problem. Now do you suppose you could write me a WEP cracking utility?

Also, maybe a utility that will capture the MAC addresses of wireless devices nearby?

Just kidding...

Hey Erica could you make it so it remembers multiple MAC addresses?
