iPhone IPhone 3GS 4.1 won't allow manual upgrade to 6.1.2, why?

[Cubytus]

Tethered would mean that, each time the battery dies, one would have to restart the whole process again.

If phone loses 3G connectivity, or can't hook on the network (happened on a couple of occasion), the easy solution is to start by rebooting it. With thethered, not so much. Considering how fast an iPhone 3GS discharges, it seems to be major drawback.

true but there is the option to semi-tether the device which at least makes it slightly not so bad

Can you get an unlock from IMEI or carrier?

Cydia automatically gets the current shsh being signed even if its not the currently installed version. So if you used cydia while 5.1.1 was being signed, then cydia may have the correct shsh.

You generally get the unlock through the carrier by giving them the IMEI number. But there may be ways around it on eBay

Yes, you can open cydia and check what shsh tickets cydia has for you (only valid shsh are shown for the device in the case of iOS 6 blobs)

I repeat: I didn't use Cydia. As stated in the previous posts, iFaith revealed this iPhone 3GS only has iOS 4.1 and 6.1.3 SHSH blobs.

As for the carrier unlock, I have no idea who would have been the original carrier. Any way to tell?

What would be the exact difference between tethered and semi-tethered jailbreak?

That means you are ONLY able to restore to 4.1 and 6.1.3. iphonefrom.com not sure if that would help

You know you can google to learn more yourself, right? Here's what I found just typing tether vs semi tether in google search http://www.idownloadblog.com/2011/10/22/untethered-jailbreak-vs-tethered-jailbreak-vs-semitethered-jailbreak/

Thanks for restating what we already agreed upon many posts ago.

According to this site, this white iPhone may be either:
UK: Apple Store, O2, Three, Orange, T-Mobile, Tesco, Vodafone
Ireland: Apple Store, O2, Three, eMobile, Vodafone, Meteor

How am I supposed to find where it came from?

Google doesn't give consistent results, so I have learnt not to rely too much on it.

just repeating the fact you cannot restore to 6.1.2 because in your previous post, it implied to me you were still trying to get an untethered jailbreak by restoring to 6.1.2

honestly speaking, i don't know how you can find out which carrier the device is locked to. are you not able to do a software unlock using ultrasn0w? check if your device is eligible for the ipad baseband. if your device is eligible for the ipad baseband, then you can rely on ultrasn0w to software unlock. NOTE: FLASHING THE IPAD BASEBAND WHEN YOUR 3GS IS NOT ELIGIBLE FOR IT WILL "BRICK" THE DEVICE

it would still be best if you did some research on your own as not everyone is just going to feed you information. if you researched enough, you would find a general consensus as well as the more reputable websites

As I read it here, I could very well restore and unlock my own black 3GS to 6.1.2 untethered since I have SHSH blobs saved for it.

The white 3GS is already software unlocked, but unfortunately is stuck with iOS 4.1. Any recent application requires at least iOS 5.

From this link, this iPhone 3GS seems to have been built week 18 of 2010 (serial xx018ZFMxxx), and therefore should be compatible with iPad basebad. For comparison, my own 3GS (xx051RTLxxx) had an iPad baseband for unlocking purpose. It didn't brick it, but was very unstable and made battery die within hours. All reverted to normal when I put back the original baseband, and it kept the unlock.

On the other hand, are you implying that I could install an iPad baseband, unlock it with ultrasn0w, and add iOS 6.1.3 on top of it, then reverting to the normal baseband, all while keeping the unlock?

Really weird...

I just receive a 3GS with 4.1 and iPad baseband... it's not jailbroken but it has service and works flawless (most say that this is a Brazilian phone working on a Mexican carrier).

So the question is... how to upgrade to the newest version possible without loosing the unlock?

The device don't have any SHSH blobs saved.
The device has New Bootrom.
Don't really need to be jailbroken, as long as it keeps the unlock.

Any help will be appreciated...!

Use sn0wbreeze to upgrade to 6.1.3 and preserve the ipad BB

To unlock the ipad BB you need to be jailbroken to install ultrasn0w for the unlock.It will be a tethered JB

Alternative is an IMEI permanent unlock from either the original carrier or a grey market online onlock.

Without shsh's only choice is 4.1 or 6.1.3

Tethered is not something I am looking for, and probably neither do Probo. On my own 3GS the battery is so weak that I can't figure out if it will die at 75%, 30%, or 48%. Lucky I have an untethered unlock.

The first time I see someone admitting that third-party iPhone unlockers are grey-market. So I believe they are not asking for carrier's permission. Hence my very first question in this topic: how do I actually "get the keys" to an unlock, considering grey-market unlockers massively do it?

Without shsh's only choice is 4.1 or 6.1.3

It seems the original unlocker haven't saved this SHSH. I can't blame him since it is far from obvious.

Get a job working for the particular carrier or find someone who does.
No other way to "get the keys".

 

[TriJetHero]

It looks like you're a bit confused about different items

An jailbreak is not the same as an unlock
A JB can be either tethered or untethered
An unlock does not do untethered or terhered, it might be permanent or it might be a soft unlock with ultrasn0w

You don't get 'keys' for your unlock, either the carrier or graymarket get your IMEI listed on Apple's whitelist for unlocked phones.

Do some thourough research before attemting anything.

A tethered JB is not that bad and on 6.1.3 i would take that anytime over a 4.1 untether.

 

[Applejuiced]

Well said, he's very confused.
More research should be done on the topic by the OP.

 

[Cubytus]

In the technical support division, I guess. BTW if it's not authorized by the carrier for specific clients (as opposed to massively), it is black market.

Well, I mixed up two words from previous reply. The inconvenience stays: when you don't know when the battery will die, it's more than an inconvenience having to haul the computer and keep everything prepared for an unexpected (long) reboot that will imply switching SIM cards, wait for the JB to be applied, then the unlock.

You don't get 'keys' for your unlock, either the carrier or graymarket get your IMEI listed on Apple's whitelist for unlocked phones.

Translation: you suggest that anyone who wishes to unlock its phone work in the tech support division of the carrier.

FWIW I started doing research. By starting this topic

Long reboot???

Couple of minutes at the most, just keep your phone charged and iOS 6 brings so much more, let alone uptodate app support, almost all nice apps in the appstore and in cydia require at least 5.x

It's greymarket not blackmarket, otherwise it would be illegal which it is not.

Up to you

Yep, pretty much

Never said it wasn't good. Only that older batteries tend to die unexpectedly during normal usage, and not being able to foresee that is a major inconvenience, especially when running a tethered JB upon which the unlock depends.

Yep, pretty much

As said... It is theoretically illegal because it violates the employer's (carrier) contract, the carrier not being compensated for the unlocks issued (remember they ask $50 for each unlock), presumably, and this isn't done with the carrier's permission.
