iPhone 4 with iOS 5.0.1 (4.11.08 Baseband). What are my unlocking options?

Hi,

As stated in the title, what unlocking options do I have for an iPhone 4 running iOS 5.0.1 with the 4.11.08 baseband?

If it isn't unlockable, what's the latest unlockable iOS and baseband combination I can use to unlock this device?

Is it possible to downgrade the baseband?

Thanks to anyone who can help out.

With the information you provide, there is no option for you to unlock this phone. So, enjoy your ipod touch for now.

1. Ultrasn0w works on Iphone 4 with 01.59 baseband. Yours is 04.11 and therefore, it does not work.
2. Gevey sim only work on Iphone with baseband of 04.10 or lower. Yours is 04.11 and therefore, it does not work.
3. Iphones's baseband can't downgrade (Period), except small quantity of 3G phone with 05.08 bootloader.

Zero options now and most likely forever. So your only option is to sell it and buy a factory unlocked device.

How are you so sure that an unlock will never come out?

No options at all for now.

There will be one. Just give it time.

Simple, common sense. Both the software unlock was developed when unlocked phones were rare, particularly in the US, and getting them unlocked was impossible. Now there are factory unlocked phones on multiple carriers for people who really need them. Why would the Dev Team devote scarce resources, i.e., people, to look for exploits in the newer basebands when they are having increasing trouble finding iOS exploits? But feel free to wait for a software unlock.

How are you sure that an unlock will come out? It has been a long time since the dev release an unlock for iPhone 4 and it's not as easy to unlock than to JB.

So I tried jailbreaking my 04.11.08 Iphone 4 with redsnow 0.9.10.b3 and was able to it to install cydia, but when i try to install tetherMe i get the error message "subprocess extra-installation script killed by signal (Abort trap). So i am guessing the jailbreak was a failure? What exactly does this mean?

thanks

No, the JB wasnt failed or has nothing to do with a cydia package not installing right.
Are you installing the legit Tetherme package for 5.0.1 or any other older or hacked version?
Stick with the official tetherme from its proper repo. It installed fine on my i4 on 5.0.1

I must have assume it did'nt work the first time. I went back to settings and TetherMe was right there, which I edited to fix my mms. My question now is why did it work for me and not others. Everyone is saying there is not jailbreak for the 4.08.11 baseband. Still I'm not complaining.
Thanks.

The baseband version has nothing to do with the jailbreak.
Bb has to do with unlocking. 2 different things.

I have been waiting since October and it's looking like there won't be any unlocks until a different firmware version comes out.

My recommendation is to sell your phone, put money toward buying a factory unlocked phone. There are lot of people waiting and waiting long before you. Last software unlocked on Iphone 4 baseband 01.59 was more than 1 year ago.

Option

I have the same problem, mine is locked to at&t. But I am using H2O wireless which runs on At&t's network, might want to check into it if u are on AT&T network. $60 a month unlimited talk & text with 1 gb data a month. It is not a lot of data but it works until a unlock option is available.

I am using Straight Talk, which is also on at&t. so i was only successful in jailbreaking my 4.11.08 Ip4. All i wanted was the ability to enable MMS. I think its a good deal for $45. I use just about 2GB of data every month.

You cannot unlock it.
There's nothing available that will unlock that baeband at the moment.

Where's the best place to keep an eye on updates about an unlock for 4.11.08?
Are any reliable devs officially working on one that I can follow on twitter or something?

If its released, it will most likely be on the front page of macrumors and every other iOS/apple blog. It will be big news.
