U can upgrade ur Iphone4 to iOS 5.1.1. For that u need to preserve ur baseband so that u can use it by using gevey sim.
First download the iOS 5.1.1 firmware and then latest redsn0w.
Then open redsn0w, go in extras, then create custom firmware.
Once custom firmware is created u have to put ur Iphone into DFU mode using redsn0w. Then open iTunes then restore ur Iphone using the custom firmware created. To restore press SHIFT +RESTORE then browsed for the custom firmware.Once it is done u can jailbreak by using redsn0w. Then insert gevey sim,follow instructions .. Ur done!!!!!

U may want to call AT&T and see if u can get it factory unlocked. U don't have to have a account with them at all. The phone has to be 2 years old thow. And a few other things but they should unlock it. Then u won't have to use a gevey sim and can update freely.

I just called yesterday and got one unlocked they said they look at the first time the device was activated. So if the device is 2 years old and the account it was first activated on is in good standings it should be fine. He don't even have to be with AT&T to get it unlocked. I would give it a shot. U have nothing to loose.

I know that part, I'm just saying. You used to have almost no problems doing, now that the policy has changed it's a bit harder to do.

Well, you did a major no-no. You can't just upgrade an unlocked iPhone, you have to preserve the baseband so it can be unlocked. And it won't work with any other SIM card because you updated it....
Which iPhone do you have and what baseband is it on?

Boss my i phone is 4 and baseband build 9b208. If i cannot unlock is there i can use my iphone 4 to ipod or app wifi only. Thanks

So it's asking you to activate it?
Try hacktivating it with redsn0w so you can bypass the activation.

Terrible mistake, and only to find out that his BB is 4.12.01 now. Sad, very sad

Huh? That didn't really make sense.
And as far as your iPhone unlock, forget about it. Your not on an unlockable baseband anymore.
07-02-2012, 02:39 PM #18
So even i cannot use iphone to as a ipod
07-02-2012, 02:40 PM #19
You can use it as an iPod. Just hacktivate it with redsn0w and you'll be good to go.
