Thanks to Semaphore (creator of tiny umbrella) for this information:
It seems that Apple has decided to put a baseband requirement on iOS. So at this point, if you are using Saurik’s server or tiny umbrella and trying to restore 4.2.1 on an iPhone 4, you will end up in recovery mode and tiny umbrella will not be able to pull you out of recovery. In this case, you will have to restore 4.1 again or you will have to restore 4.2.1 stock and be tether jailbroken. (Of course, I recommend 4.1 and not bothering with 4.2.1 at all). If you are an unlocker, this is a no brainer. Do not update to 4.2.1 even to test it at this point.

iOS 3.1.3 Ftw! lol
November 23rd, 2010 at 4:36 pm
Thanks for all your hard work, everyone does appreciate it, even if some are impatient
November 23rd, 2010 at 4:47 pm
Bah, iOS 3.1.2 FTW!
4.2.1 is pretty neat on the iPad though ;)
November 23rd, 2010 at 5:43 pm
Why go to war you cant win? This is a futile exercise for apple. Cant stop jailbreak community:)
November 23rd, 2010 at 6:59 pm
hello guys. Any news on 02.10.04 unlock?
November 23rd, 2010 at 9:40 pm
This is false. I have successfully updated from 4.1 to 4.2.1 and retained my 1.59.00 baseband. Redirect to Cydia’s servers yourself and don’t use TinyUmbrella except for booting out of recovery mode. Make sure the service is off and your host files are redirected to Cydia’s servers. You should get error 21 if you are trying to use TinyUmbrella to restore, which will have done nothing whatsoever to your phone except put it in recovery mode, and you will get error 1013 if you do it the way I explained above, which is a baseband update error. Just use TinyUmbrella to kick it out of recovery mode and your phone will be fully functional.

I really hope in the future the major iPhone hackers (Dev Team, comex, geohot, etc) will release a CRACKED iOS+BB.
Instead of having us go through all the trouble of activating, jailbreaking, unlocking, and enabling all disabled features, they could do this in advance and make available only the software for us to install.
We must also evolve because Apple will keep making hacking more difficult.. greedy bastards.
November 23rd, 2010 at 10:15 pm
you work for apple. it dont fool us.
November 23rd, 2010 at 10:19 pm
any news for 02.10.04 unlock at 4.1 or 4.2?
November 23rd, 2010 at 10:53 pm
if only i could afford one..
November 23rd, 2010 at 11:33 pm
I can confirm that AppleHack23 is correct. I am currently on 4.2.1 and baseband 01.59.00.

LOL
November 24th, 2010 at 2:41 am
does anyone know what basebands use 4.2.1? iphone 3gs, i4.
November 24th, 2010 at 3:49 am
http://en.wikipedia.org/wiki/IOS_version_history#4.2.1
November 24th, 2010 at 3:55 am
They can’t do that because it would be a violation of apple’s iOS liscencing agreement.
November 24th, 2010 at 3:57 am
On iPhone 4 with 4.2.1 baseband is 03.10.01
November 24th, 2010 at 4:01 am
They can’t, because hacked firmware includes Apple’s code which gives Apple an opportunity to sue them.
November 24th, 2010 at 4:02 am
The 3G and 3Gs will get 5.15 baseband with 4.2.1 update. Unlockers should not go near since even BB 5.14 is unlockable right now.
November 24th, 2010 at 4:03 am
They can’t distribute Apple’s code.
November 24th, 2010 at 4:08 am
i think its 05.15.04
November 24th, 2010 at 4:23 am
Thank you for the update Big Boss and secondly I do not think this baseband thing would affect unlocked phones?
November 24th, 2010 at 4:24 am
Sorry I meant FACTORY unlocked phones!
November 24th, 2010 at 6:50 am
This would actually be illegal while jailbreaking has been ruled legal .
November 24th, 2010 at 7:04 am
very sensible though.
thanks for the Information.
also how to install to 4.2.1 from 4.0.1 (3gs) without updating baseband? thru pwnage?
November 24th, 2010 at 7:33 am
They can “generate” the image on your PC. That’s pretty much what pwnage tool does.
November 24th, 2010 at 8:03 am
If anyone releases a cracked version of ios they will be expecting a HUGE lawsuit from apple. Its highly against the law to violate copyright shit.
November 24th, 2010 at 8:37 am
its forever unlocked
November 24th, 2010 at 8:58 am
I think Customers who have paid a full price to purchase the iPhone in the USA or any other country where Only Factory locked iPhones are soled, should have the right to get them unlocked by Apple or the Mobile carrier.
I know for a fact that there are special codes which can be entered into the iPhone that unlocks it permanently.
Q:How do I know this you ask !
A:I work in a Telecom and I’m aware of this :)
November 24th, 2010 at 9:47 am
This won’t happen because of legal issues (changing Apple’s software and then distributing it for download).
November 24th, 2010 at 10:52 am
iDle! you work in the telecoms indutry but dont know anything mate, I too work in this industry and i tell you now that there are NO codes that can be entered into the iPhone to unlock it. the Unlock is COMPLETELY server based, meaning that Apples servers have to have the phone IMEI listed on their records as unlocked, so everytime you connect to iTunes to reflash/upgrade etc it keeps it unlocked!
BR
November 24th, 2010 at 11:09 am
RoX,
I agree with you, however here is s scenario that happened with a friend of mine who works at another telecom:
He bought an iPhone 4 from the USA and paid full price without having to sign an AT&T contract, however he was using an AT&T SIM, his company sent him to Germany on a business trip, before that he was sent to the Tech department in his company who contacted Apple and provided them with those special codes which includes some digits from his iDevice.
After that the iPhone is fully unlocked as he have updated the iOS twice with no issues while using other SIM’s than AT&T.
now tell me thats not possible !
November 24th, 2010 at 11:20 am
Well at this point guys Ill be the ginny pig and like an idiot I updated to 4.2.1 on my 3G I really wanted to see if there was an improvement in speed But NO still the same crap. I really recommend 3.1.3 for all 3G users Also this update updated my baseband to 05.15.04 so now Im even more screwed in witch Ithink there will be no unlock for that baseband.
November 24th, 2010 at 12:20 pm
iOS 3.1.3 is best for 3G/3Gs
as for the BB unlock, don’t lose hope just yet ^(~
November 24th, 2010 at 3:21 pm
That is not possible
November 24th, 2010 at 4:41 pm
If you try to install de 4.1.2 and it stucks while installing all you have to do is yo use irecboot and enter recovery mode, then, after the reboot of the phone and the iTunes logo shown up, use exit recovery mode, and voila, 4.1.2 installed…
November 24th, 2010 at 5:30 pm
I don’t get what you mean about the BB 5.14 being ‘unlockable’?
November 25th, 2010 at 12:49 pm
Save up, and get one when you have enough.
November 25th, 2010 at 1:16 pm
Any good new about 4.1 with baseband 2.10.4?? how can i unlock it??
November 25th, 2010 at 5:58 pm
i have too 4.2.1 (iPhone 4) and i preserve 01.59.00
November 25th, 2010 at 10:50 pm
How?? can u tell us!!
November 26th, 2010 at 8:33 am
That´s interesting information, iDle, but what can be done about it? Nothning, that´s the answer. I leave in Africa and bought a Iphone4 in the US not aware that it was locked (I may have not have communicated properly with the sales agent at Apple Store, as when asked I said I did not want it activated to ITT, and she didn´t mention I coudnt use it eslsewere). I´m now stuck with an expensive Ipod. I made a firm resolution NEVER to buy ANYTHING Apple again.
November 26th, 2010 at 12:25 pm
Wait about two weeks!
November 27th, 2010 at 10:24 am
I work for a mobile operator in the uk and if you contact your operator over here and pay £20 they will send the details to apple for them to unlock your iPhone via iTunes
November 29th, 2010 at 12:28 pm
Ashton,
Thats what I’m trying to tell the people on here, but no one seems to believe me :(
On the other hand this hasn’t been standardized yet, and consumers should sue apple/telecoms to do so when you purchase the device without a contract (Fully paid)in countries who only locked devices are soled (Monopolized).
November 29th, 2010 at 1:59 pm
You think there will be ultrasnow support for 05.15? Or the only way to unlock will be to use ipads baseband?
November 30th, 2010 at 4:51 am
Unofficially yes.
Just keep in mind that you’ll be stuck with it till apple comes up with a baseband higher than that later on if you plan to upgrade using a iTunes for a legit firmware.
November 30th, 2010 at 1:10 pm
Big good
December 1st, 2010 at 3:04 pm
yippy ireb did it on 4.2.1 to get outtta recovery mode and made me frightened too of green screen of life ,and i downgraded my iphone 3g to 4.0 with stock fw from ios 4.2.1
December 5th, 2010 at 7:01 am
The update works but when restoring it won’t.
December 5th, 2010 at 2:18 pm
Hi I’m new to this so please pardon me If this is a dumb question. I have an unlocked iphone 4 jail broken through jailbreakme.com 4.0.1 with 1.59.0 base band. Is it ok to update 4.2.1 yet?
December 6th, 2010 at 4:36 am
If it’s Officially unlocked iPhone Yes, however if you plan on to jailbreak it again keep in mind that the current available jailbreak for iOS 4.2.1 is tethered; which means you’ll have to connect it to a PC and use redsn0w/PWNtool to turn it on when it goes off.
December 8th, 2010 at 6:37 pm
I gottaa a iPhone 3GS, I just updated my iPhone to iOS 4.2.1 with baseband 05.15.04, how can unlock my phone ???? Anyone pls help
December 9th, 2010 at 7:36 am
If you’re iphone has an old boot ROM, then you have a good news, if new boot ROM, not very good news, however; I assume since you’re seeking an unlock it is a none official unlocked iphone, so you’ll have to use the latest redsn0w/PWNtool to update your baseband to the iPad baseband then unlock it with ultrasn0w 1.2 which is inside cydia.
Just keep in mind that you’ll be stuck with your current iOS version until apple releases an iOS higher than 6.x
now going back to the good/bad news, old boot ROM the JB is Untethered, the new boot ROM is tethered.
I hope you find this info useful and Good Luck :)
December 11th, 2010 at 2:13 pm
uhm I have a 3g iphone and I’m planning to upgrade it to 4.2.1 BUT I’m scared to do so. Will it upgrade to 6.15 baseband?
December 14th, 2010 at 6:39 am
mae,
If you want a Good advice.
the best iOS for iPhone 3G is iOS 3.1.3
Regards
December 24th, 2010 at 9:54 pm
Hey.. I’ve got 3G updated to 4.2.1 BB 05.15.04 … What’s the easiest way to unlock ? Thanks
December 26th, 2010 at 6:26 am
Alix1,
You have limited options;
1- Use the latest redsn0w to update the baseband into the iPad baseband 6.x.
2- Downgrade your iOS to any previews one, however you still need to get the iPad baseband.
December 29th, 2010 at 12:51 pm
I believe you
January 3rd, 2011 at 9:36 am
You get round that by distributing a PPF only
January 6th, 2011 at 4:12 pm
Yeah
January 11th, 2011 at 2:34 am
I cannot upgrade my bb 3.10.01 to 6.15 because there is no choice to be checked upon with my redsn0w though it is in it’s latest version. Why is this so and what should I do?
January 11th, 2011 at 3:08 pm
i have iPhone 4.1 3gs, 05.14 updated to BB 06.15xx with redsnow, unlock w/ ultrasnow, run w/ (SAM) but stil battery drained fast.
anybody knows how to fix this battery drained????
January 11th, 2011 at 3:15 pm
upgrading to BB 6.15 is only for 3g(s) bb 5.14 & 5.15
January 16th, 2011 at 4:38 am
Hi,
You either have to do the whole thing again and remember to use tinyumbrella to kick out of recovery due to the error you’ll get because of the BB.
Otherwise if you’re sure everything you did was right, then control the usage of ” Notifications, Location service, and 3G ”
Good luck :)

jean,
No such baseband; Unless you mean 03.10.01 !
you’re iPhone can be jailbroken, however that baseband cannot be unlocked currently.
July 30th, 2011 at 8:25 am
