I could change the wifi MAC address on a 2G iphone in terminal with the ifconfig command provided by network-cmds. This does not work on 3gs and wonder if anyone found a way. I googled and find others having the same issue, but no solution.

Thanks

Moderators: I realize I posted this in the wrong thread and don't see an option to move it. Please move it to the 3gs general talk area, as I did not intend it in the 3g general talk area, and then delete this post asking you to move it. Thanks.

As far as I know, the way to do this is via iRecovery. Replace the 0-F with the mac address you want.

Put iPhone into recovery mode (not DFU)

Connect with iRecovery and run the following:

Code:

setenv wifiaddr "0123456789ABCDEF"
printenv wifiaddr
saveenv
fsboot

Thank you for your reply.

Could going into recovery mode cause me to need to do a restore? I have a 3gs that is jailbroken and unlocked in 3.1.3 and I CANNOT restore firmware on it because I want to stay in 3.1.3 and I do NOT have SHSH blobs for 3.1.3.

Also, I was seeing elsewhere that the wifiaddr command causes other issues such as problems syncing in iTunes. It seems that the use of iRecovery is intended to stop this problem, but would like to hear from others before I try it. Also, I wonder why people have had issues with iTunes. Does iTunes send this address to Apple? Can I prevent the new wifi mac from being sent to Apple.

It seems from this article, I can do it in Terminal on the phone, if I am willing to reenter the original Mac address before syncing to iTunes. Would that be correct understanding?

nvram at the OS level does the same thing as the command in iRecovery.

You won't screw up your jailbreak by forcing it into recovery mode and then making the required changes

As for changing the wifi mac address - yes anything that has already used the MAC address as a unique identifier to for example create a pairing relationship. This may be the origin of the iTunes problem you describe. A simple fix would be to set the iPhone up as new and resync with iTunes.

So does this all mean, I can just use terminal on the phone (and forget iRecovery and going into Recovery mode)? I have everything I want to sync to the phone on my computer, and wouldn't care if itunes decides its a different phone the one time and erases and reloads everything to the phone, the first time after I change the wifi Mac Address, as long as there are no other problems. Or am I missing something?

i have been trying to change my 3gs's mac address which is ios 4.1 and i am running windows 7. i got libusb installed.

i can get into recovery mode and connected with irecovery but cant run any command except reboot.

printenv doesnt show any result/output

other commands doesnt show any output as well.

tried in another pc with xp but same result.

any idea?

cheers
