1.You can update without any problem.Hi guys, I have a question which is if I get a factory unlock on my iphone 4 from AT&T does that mean I have to update to ios 6 or can I just stay at 5.1.1?
If I have to update is there any way to go back to ios5.1.1?

1.You can update without any problem.
2.Downgrade you need SHSH file,how to get him?
Stay in 5.1.1 and use redsh0w for jailbreak.
Run Cydia lake user. Your SHSH file saved on Cydia server.
I'm still confuse as to what your saying. So I can factoy unlock my phone without updating to ios 6?
Factory unlocks you can make for any version of iOS.That's mean you can use your iPhone with another GSM carrier .
Plug in to iTunes to show the mess that your iPhone has unlock,but not strongly to update,only ask you if you want.That I know but when I get the factory unlock I have to plug it into itnes right and wont it make me restore and force me to update to ios 6. Am I correct?

AT&T now tells you to just submit a form on their website to do factory unlock, FWIW: att.com/deviceunlock
(I used this process successfully a few weeks ago when selling an old iPhone)
Yes, I know exactly how long it took because I submitted a request through that site a few weeks ago when I sold an old iPhone.
I received a response that they'd received my request just a short time after submitting it. It estimated 5-7 business days until complete. Then I got an email 5 business days later saying it was complete, and I could now restore phone as new in iTunes and it'd be unlocked.
