iPhone 4S Owners Hoping to Eventually Unlock Should NOT Update to iOS 5.0.1

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.

For more updates you can follow us on Twitter, Facebook, RSS, or check out the new iClarified menu bar app.

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.

DT - I do not lick dicks. Therefore, it is obvious that I am not Unlock.

Unlock - January 19, 2012 at 7:25pm

Phil, thats just because your mom does it for you.

qw1987 - January 19, 2012 at 7:53pm

Certainly everyone else on here agrees with it. The rest of your comment I cannot address since it made absolutely no sense.

qw1987 - January 19, 2012 at 7:56pm

i agree that unlock sucks dicks (so does phil)

You guys are too much fun. Maybe I'll start reading the comments more often.

Wtf, my 3GS has been "locked" for almost 2 years. It's the most expensive paper weight I have ever seen.

doug - January 18, 2012 at 7:04pm

how do you downgrade to 9A405?

Tomy - January 18, 2012 at 7:25pm

Thats what MusleNerd mention,if your iPhone 5.0.1 (9A406) go ahead find the 5.0.1(9A405) at the link where it say "here" with dark letter

doug - January 18, 2012 at 7:32pm

I downloaded the firmware 9A405. How do I apply it? Thanks

JBO - January 19, 2012 at 4:05pm

all you do is plug in your phone and hit shift and click restore and find the ipsw file!

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.....

Sory wt th spelling,I punch it right but got wrong words....lol

Frank - January 18, 2012 at 5:00pm

You can't downgrade to iOS 5.0 because Apple is no longer signing the firmware. Just stay where you are (9A405).

Andreas - January 18, 2012 at 8:57am

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?

iph0ne - January 18, 2012 at 2:01pm

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.

Axe - January 18, 2012 at 2:05pm

Yes it's true. 906 & 905 has different baseband 1.0.14 & 1.0.13. So rule of thumb is stay at 1.0.13.

Andreas - January 18, 2012 at 2:19pm

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.

Hash - January 18, 2012 at 2:52pm

Yeah, can someone verifty this?

Hash - January 18, 2012 at 4:14pm

Agreed.... Unlocked is great for traveling purposes. And also for re-sale.

Phil - January 18, 2012 at 6:41pm

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.

Unlock - January 18, 2012 at 6:49pm

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.

qw1987 - January 18, 2012 at 6:54pm

Sorry Unlock, but it is YOU who don't know what you are talking about. You are living in the past. What you say is no longer true, in ANY market.

Unlock - January 18, 2012 at 7:08pm

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.

qw1987 - January 18, 2012 at 7:47pm

No. I am just not willing to scam somebody selling them an 'unlocked' phone, knowing that they don't know that they are being misled.

Unlock - January 18, 2012 at 8:31pm

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).
