Iphone 4s Unlock Methow ?

Usually unlocking an iPhone 4 or 4S is tricky. Usually baseband is troubled and users have to jailbreak and make sure they preserve their baseband. As of today November 18th There is method to unlocking an iPhone 4S without a jailbreak or any specific modding! ITs actually quite simple of you follow the tutorial below:

Insert original carrier AT&T SIM card
Dial 611 for AT&T customer service hotline and drop the call
Turn on Airplane Mode
Take out AT&T SIM card
Insert T-Mobile SIM card
Make sure WiFi is off ( also tap on ‘Forget this Network” to make sure it doesn’t connect automatically later)
Switch off Airplane Mode and iPhone will search for network. This is followed by the Apple splash screen appearing.
Activation Required will be displayed on the screen
EDGE network will activate automatically – notice the ‘E’ on the top left corner of the screen
Wait for about 20-30 seconds and turn off the phone
Turn on iPhone and the same Activation Required screen will be displayed
When you see one signal bar, tap on Use Cellular Connection
Eject SIM card
Activation Required screen will be displayed the second time
Insert SIM card
Unlocked!

I had a lady come in to my store a few days ago with an iPhone 4S that she said was unlocked. I didn't think they came unlocked but I put in one of our micro SIM cards after moving her account to it and it worked perfectly.

She told me she bought it off Amazon and it came from Europe somewhere.

I'm highly skeptical about this unlock bug: a) actually working; b) persisting through a restore (or even a reboot). Still intrigued though...

I need to try this, would be great if it works.

Would it be totally unlocked (so you could use it on other carries outside the US) or just useable on TMobile?

In the video, his comment was "that it only works for a short amount of time from seconds to minutes".

I'm highly doubtful that a software bug (much less such a facile one) would allow a permanent carrier unlock, but if it functioned on T-Mobile, then yes, it would be unlocked outside the US too.

Anyone have success? I'm having issues doing this to my 3GS. Whenever it ha no service or no sim, it still says AT&T in the corner (without bars). I am in the process of downloading 5.0.1 so I can restore it and get this to work. I am going to israel soon and would love to be able to take my 3GS instead of my old 2G.

Why don't you just install the 06.15.00 baseband and jailbreak it if you have a 3GS..
