Contrary to many reports, iPhone 4S owners hoping for a future unlock should not update to iOS 5.0.1 but instead stay on iOS 5.0 to maximize their chances of an unlock.
MuscleNerd has confirmed to iClarified that an untethered iPhone 4S jailbreak for iOS 5.0 will be released at the same time as the iOS 5.0.1 jailbreak, or a day or two later. As always, for those looking to unlock, it is standard operating procedure to stay at the lowest possible baseband.
In fact, its recommended that those already on iOS 5.0.1 should check their build number and downgrade from build 9A406 to 9A405 while Apple is still signing both builds. Due to differences in the basebands, its more likely that an unlock will be found for the earlier build than the later. You can find direct firmware download links here.
We can't guarantee an unlock will be found for iOS 5.0. However, in November MuscleNerd revealed that an unlock was looking 'very promising' and was able to use an exploit to dump the baseband bootrom. However, it's not clear if or when an unlock based on that exploit will materialize.

So I was at baseband 1.0.14 on my 4S 5.0.1. I then used the other firmware, there are 2 firmwares for 5.0.1 on a 4S, to get my baseband down to 1.0.13. How the hell can it work like that? I'm glad it did, but how? I always understood that it is difficult next to impossible to downgrade a baseband - for example anyone stuck on ipad baseband who might want to downgrade back to whatever stock firmware/baseband. No utility required, just a simple restore from itunes with the phone in dfu. If that worked so easily why can't I install an older firmware on my mother's 3GS and thereby downgrade the baseband?
This is great news for a person who do business travel a lot like me especially out of the country. I will definitely save some dollarsl. I hope this one will be a reality in the near future.
To iClarified,I hope you edit the comment that ppl saying their name under different persons name,I read this cmmnt hv'g name:Benedikt/Tim Cook & Our Dev-Team MslNrd...we as the ppl that need guidance getting wrong idea fr this names.so pls update the cmnt if they r true under that name,so we can get right info. Thx much iClarified.
Ha! I knew it I am glad I didn't update my Iphones4s last nite almost did.
I am still on 5.0 ..
5.0.1 still has a battery problem..sisnce I updated my iphone4 for my daughter the battery sucks..I took it to apple they said they knew about the firmware problem they are releasing a new firmware that would solve the problem
Hi MuscleNerd,great to have you weitting cmnt in here. basically I hv my i4S on 5.0 (.9A334),then whn the news showed us to upgrade,I upgraded to 5.0.1 straight fr my device (on update software),its becouse I can't find the iOS thru iClarified at that time. Do it did upgrade to 5.0.1 (9A405) not to (9A406)...,but th BB got upgrade too to 1.0.13... & I got TU saved my Blop. Now if I downgrade to 5.0,would be possible to get Unlock with th 1.0.13 ?...Thanks much.....
Confusing article. Is it really possible to downgrade your baseband?
If it's true that there are different baseband versions between build 9A406 and 9A405, then why downgrade to 9A405 if it will not downgrade your baseband at the same time?
didn't try it out yet but it probably will downgrade the baseband. And that is only possible because apple is still signing both firmware versions and therefore both basebands.
Yes, I understand it is possible to downgrade as long as Apple is still signing both 9A405 and 9A406. My question is: Will this downgrade your baseband as well once you have upgaded to the latest one??
My understanding is that you can never downgrade you baseband the same way you are downgrading the firmware.
What a pile of horse crap! A factory unlocked phone IS worth significantly more. Hacked/software unlocked? Maybe that will get you a couple more dollars, but that's it.
Sorry Phil, you don't know what your talking about. I sold my iPhone 4 for $150 more than my wife's because mine was software unlocked. You just gotta find the right market.
Really Phil? Cause I just did that just over a month ago. You gonna tell me it's changed that dramatically in a month? Just cause you can't do it doesn't mean no one can.
Cant prove me wrong? Run out of ammo? Buh-bye! Don't let the door hit you on the way out. (by the way, Craigslists posts don't identify me... Clueless yet again).
