Hi! I have unlocked two iPhones now. Both were activated with iNdependence, and one was unlocked via iUnlock and one with anySIM. Both work just fine.

HOWEVER, whenever I switch SIMS between carriers, I have to re-activate the phone. I'm on AT&T and my wife is on T-Mobile, so I'd REALLY like to be able to just switch between the two without having to re-activate.

Does anybody know how to do this? I've heard that many people don't have this problem, but I can't seem to find any instructions for how to solve it.

Thanks for any help.

Download and install the patched lockdownd. The serahc button should help you find it in the forums.

Once you install the hacked lockdownd, then each time you want to switch SIMS, hold the power button for ten seconds, slide the red slider and restart your phone. Enjoy.

Yeesh, I should have known to do that. Did that the first time I unlocked the phone, but didn't do it after I had to do a restore.

Thanks! Worked perfectly. And for the record, once I installed that lockdown file, I don't need to power down the phone to switch sim cards. I just pop one out, pop the new one in and start dialing. Testing it several times and it works perfectly!

Thanks again for the prompt response. I appreciate it.

could you post the link to that lockdown patch?

I got it from ModMyIphone.com. Link is here
