Firmware 1.1.3
This firmware was released on January 15, 2008 and added a few features. This firmware is unlockable. It's best to just restore to 1.1.4 and unlock on that firmware.
Downgrade path: 1.1.1 firmware (recommended), 1.0.2 firmware (if needed). Upgrade path: 1.1.4 firmware. Restore path: 1.1.3 firmware. Unlockable: Yes (bootloader 3.9 and 4.6). For 3.9 bootloaders you are only updating the firmware therefore no change is made to the baseband so your previous unlock will remain intact. For those on 4.6 bootloaders use my tutorials. You can them here. Jailbreak/activation/3rd party applications: The best method for peforming this (3.9 bootloaders) is to follow my OS X and Windows tutorial here, If you have the 4.6 bootloader use my tutorials. You can them here. Unmodified: If you have never hacked/modified or unlocked the iPhone before then you must downgrade to 1.1.1 firmware and jailbreak it to install OktoPrep. You can then update to 1.1.2, and then jailbreak it, and then soft upgrade to 1.1.3. The you can use third party programs, and SSH to customize your iPhone. AppSnapp Installer is the best method to access third party programs. Use my tutorials. You can them here. Modified: If you have hacked/modified or unlocked the iPhone before and want to restore 1.1.3 firmware: You would have to repeat the lengthy process of downgrading to 1.1.1 firmware and working your way back up to 1.1.3 firmware again. You can run the GeoUnlock program a second time in a row, it will work. Use my tutorials. You can them here. Warning: If you restore to 1.1.3 you will not be relocked, you would need to follow my tutorials and just jailbreak again, and your SIMs will work as they did before. Use my tutorials. You can them here._________________________________________
Firmware 1.1.2
This firmware introduced a new bootloader (but only if the iPhone was purchased new, and came with 1.1.2 firmware). It was released November 9th, 2007. This firmware is fully unlockable on both the original bootloader (3.9) and the new bootloader (4.6).
Downgrade path: 1.1.1 firmware (recommended), 1.0.2 firmware (if needed). Upgrade path: "Soft upgrade" to 1.1.3 is currently the best method. This will mix 1.1.3 firmware with 1.1.2 baseband. Restore path: 1.1.2 firmware. Unlockable: Yes (bootloader 3.9 and 4.6). Use anySIM 1.2.1u (add this repository (http://i.unlock.no/) to your Installer sources list. Use my tutorials. You can find them here. Jailbreak/activation/3rd party applications: The best method for peforming this is to follow my tutorials. You can find them here. Unmodified: If you have never hacked/modified or unlocked the iPhone before then you must downgrade to 1.1.1 firmware to install OktoPrep and unlock. You can then update to 1.1.2, and then jailbreak, activate, and use third party programs, and SSH to customize your iPhone. AppSnapp Installer is the best method to access third party programs. The best method for peforming this is to use my tutorials. You can find them here. Modified: If you have hacked/modified or unlocked the iPhone before and want to restore 1.1.2 firmware: I don't have a recommendation for this situation. There is no tool I know of that undoes what anySIM 1.2.1u does. Until I face a situation where I need to repair someone's iPhone that is unlocked and on 1.1.2 I don't have an opinion. Warning: If you restore to 1.1.2 I would ASSUME you will not be relocked, you would need to follow my Step 1 tutorial and just jailbreak again, and your SIMs will work as they did before._________________________________________
Firmware 1.1.1
This was the first significant update to the iPhone and included numerous features including: improved audio, iTunes Music Store, better Bluetooth audio support, video output (if the Apple branded cable is purchased), et cetera. It was released September 27, 2007.
Downgrade path: 1.0.2 firmware (if needed). Upgrade path: Directly to 1.1.2. Restore path: 1.1.1 firmware. Unlockable: Yes. Use anySIM 1.1. Will be relocked when upgrading to 1.1.2. If you restore to 1.1.1 you will not have to unlock again, just activate to get into the iPhone. Use my tutorials. You can find them here. Jailbreak/activation/3rd party applications: The best method for doing all three of these things, and it doesn't even require a computer, just a Wi-Fi signal, is with the AppSnapp Installer. This is handled at the http://www.jailbreakme.com website on your iPhone only. Use my tutorials. You can find them here. Unmodified: If you have never hacked/modified or unlocked the iPhone before (or you have virginized to restore it to factory state) you have two choices:- Stay on 1.1.1 firmware. You can jailbreak, activate, unlock and use third party programs, and SSH to customize your iPhone. AppSnapp Installer is the best method to access third party programs. Use my tutorials. You can find them here.
- Upgrade to newer firmware.
Modified: If you have hacked/modified or unlocked the iPhone before and want to restore 1.1.1 firmware there are two options:
- If you used anySIM prior to version 1.1, or used the hardware unlock method, or use iUnlocker (probably because you downgraded the firmware to 1.0.2), then you must first downgrade the 04 series baseband to 03. Then you must virginize the baseband firmware before upgrading. There are virginizing scripts on Installer. To get access to them, install (i.unlock.no) to your installer sources.
- If you used anySIM version 1.1 to unlock (and did not downgrade to 1.0.2 firmware) then you do not need to worry about virginizing your baseband prior to upgrading to 1.1.1
Warning: If unlocked with anySIM prior to version 1.1, you will be relocked when restoring to 1.1.1 firmware. Make sure you downgrade and virginize the baseband if you used anySIM prior to version 1.1 or used a hardware unlock method or iUnlocker.

The best method for adding programs is with the AppTapp program (not to be confused with the newer AppSnapp program) which can be found here.
For Windows users, the PACAY program or the wiNstaller program will jailbreak and activate the iPhone.

- If you used anySIM prior to version 1.1, or used the hardware unlock method, or use iUnlocker, then you must first virginize the baseband firmware before upgrading.
- If you used anySIM version 1.1 to unlock then you do not need to worry about virginizing your baseband prior to upgrading to 1.1.1
Warning: If unlocked you will be relocked when updating to 1.1.1 firmware. Make sure you virginize the baseband if you used anySIM prior to version 1.1 or used a hardware unlock method or iUnlocker. If you blindly update an unlocked iPhone to 1.1.1 you may get a corrupted iPhone, and as a result have this IMEI 004999010640000 set. Read this guide to fix this IMEI problem.
