If your iPhone has never been unbarred, downgrading from 1.1.3 will leave you bricked until you upgrade back to 1.1.3, as right as I can tell. The telecommunicate (even with an unquestionable AT&T SIM) reports an Wrong SIM spell iTunes says there's no SIM at no, when you've downgraded back to 1.1.1 or 1.1.2 (1.0.x young).

If your telecommunicate was unbarred, the baseband upgrade fails on 1.1.3, so you will not have this question but will not get 1.1.3 to work.

Obviously this Gregorian calendar month change once Edible fruit releases the firmware officially but I do not count that as prospective.

I don't see it event anytime soon.

The old exploits aren't here anymore. The hope would be finding an put to work in the new baseband encrypt itself to run a large large indefinite amount of encrypt. But I think the bootloader is beautiful well secured down.

First of no, downgrading the bootloader from software system is out of the question. The bootrom put to work runs before the electric current bootloader, so it can access the bootloader. But when the bootloader boots, it locks down its sections of flash. So aft the bootloader runs, the bootloader can't be touched.

Secondly, the lone secpack that validates on 4.6 is >= 1.1.3 They ready-made a change to the divide of the secpack so the elderly ones don't invalidate. So if we looked for an put to work in the baseband itself, it would have to be on post 1.1.2

Firmware is spoken as it is uploaded, and this is what IPSF and AnySim take point of. The old bootloader just relied on ready and waiting for the sig to test before activity the first 0x400 bytes, which be the start straight line. The new bootloader also needs the "secpack" in 0x3c0000 to not test. So we would have to find an put to work which can write the first 0x400 and kill 0x3c0000.

The IPSF withdraw itself uses an RSA hack in bootloader 3.9 This has been thoroughly spotted in 4.6

Also even if we remuneration a way to inhumane force the NCK's in sane time, we can't get the aggregation to do the inhumane force off 4.6 The lone hope Hera is to find the Edible fruit algorithmic rule old to give the NCK. I don't think this is possibility, unless we have a enquire in Edible fruit :)

I hope I am wrong, and no ingenious somebody will come along with a software system withdraw.

One thing about the iPhone that has miffed me has been that once it notifies you of an SMS or Telephony once, it just waits for you to pick it up and look at the home screen.

That's wherefore I ready-made the model SMSNotify, which scans your SMS info for uninformed messages, and vibrates your telecommunicate periodically when it finds any.

I'm content to declare SMSNotify for the iPhone 2.0 firmware, with the following features:

- Nowadays supports telephony. A telephony will bombilation you twice, an SMS buzzes you ternion times
- Lone buzzes when the telecommunicate comes out of period, for mental representation, when it checks your electronic mail, or checks in with the cell network.
- Full GPL source included in the bundle instal (look in /usr/local/smsnotify).

My good individual Shaun Erickson is doing the bundle manipulation, and it is nowadays easy for facility via Cydia.

I'm excavation on a Dock for firmware 2.0 but that's...

So, as awaited our friends the misfits have recently free the long anticipated 2.2 news. We can substantiate that this update SHOULD NOT be theoretical victimisation iTunes if you want the chance of a soft-unlock in the near future.

If you want to keep that derivative of a ‘soft-unlock in the near future’ easy but you want the new features of 2.2, you will be able-bodied to news to 2.2 victimisation a PwnageTool created trade ipsw file that disables the baseband news. You will be able-bodied to do this victimisation an updated turning of PwnageTool that will be free erstwhile soon.

Some facts -

• The 2.2 firmware for 3G contains a baseband news for the 3G iPhone
• The 2.2 firmware for 2G (1st information iPhones) doesn’t be a baseband news and the baseband is still at 04.05.04
• We disbelieve that our Pwnage proficiency (and therefore the Escape) isn’t unnatural, but PwnageTool and QuickPwn do not support this release as yet, so DO NOT instal 2.2 using iTunes as you will lose your jailbreak
• If you apply this news and you previously relied on PwnageTool or QuickPwn to modify your telecommunicate, it Gregorian calendar month transmute temporarily deactivated and unusable (until we release the new turning of PwnageTool or QuickPwn).
• PwnageTool and QuickPwn updates will be free as soon as possible that will allow a safe news way to 2.2 the release of these updates is fateful but not imminent, we square measure creating the modifications right nowadays and we requisite to put the new software system done the familiar experimentation process.
• If you apply this news and you have third-party (non AppStore) applications that you swear on they will stop working.
• 2G (1st information) iPhone users United Nations agency cannot act for the new PwnageTool or QuickPwn can safely “News” to 2.2 victimisation iTunes, this will preserve the extant energizing. However “restoring” to 2.2 victimisation iTunes will return the iPhone to the unactivated state. If you square measure in any mistrust just wait. NB: This deeds for 2G ONLY.
• The use of SIM-Proxies (small circuit boards/chips that sit underneath the SIM card) to provide GSM/UMTS service on your secured iPhone 3G is a performing that we have always advised against. Early reports convey that the 2.2 news disables the functionality of these inclination. The techniques old were always undependable and we square measure dumbfounded that they have lasted this long.
• We square measure not excavation on the 2nd generation iPod touch at the minute, so we cannot report on what the the 2.2 software system news Gregorian calendar month do to this general model

So, as always, if you square measure in any mistrust any gratify delay the instal of this firmware on any of your inclination until we have investigated the release in more than detail. Watch this space ;-)

Alright! Congrats to Kmac1985 from the Hackint0sh forums United Nations agency discovered this little doozy of a performing. Make sure to read the issues below (it's not COMPLETELY nonreversible). On a telecommunicate that has 1.1.1 installed:

- Start by downloading the 1.0.2 firmware here. Get it spell it's still hot. That's an Edible fruit transfer link so it's subject to change.

- Try to sit low-level a good light source. You requisite to see the screen clearly when it's not backlit.

- Make sure the telecommunicate is on and running normally (if reactive, at the Home screen, if not, just at the "Modify iphone" screen). The telecommunicate mustiness also be docked or obstructed in to your USB cable.

- Press and hold the Power and Home buttons on the telecommunicate until the screen shuts off.

- Release the Power button immediately. Keep imperative the...
