If you are using a 3G iPhone with yellowsn0w and rely on yellowsn0w to obtain cellular service, then you should NOT use PwnageTool right now. Ultrasn0w is not included with this release and therefore your baseband will be locked and unable to use an operator other than the official one it was bought for. Ultrasn0w will be release via APT (cydia and icy) soon (update: Ultrasn0w released). If you have an original iPhone (1st generation) then 3.0 unlock works with this PwnageTool release.
Yellowsn0w in its current form will NOT work with the baseband version that is present in the 3.0 update, you will need Ultrasn0w, which will be released sometime soon, Ultrasn0w will work with all iPhone 3G models (but not 3GS), even ones that were previously unlockable, Ultrasn0w will be released via APT (this means you can get it via Cydia or Icy).
PwnageTool will NOT work for the iPhone 3GS. PwnageTool WILL work for Original iPhone (1st Generation), Original iPod touch (1st Generation) and the iPhone 3G.
Yes, DevTeam released new version of their software. First of all, please, do NOT use unofficial software from unknows sites (f.e. quickpwm.com). We recommend to download from torrent or official mirors.
We regulary publish latets software and firmware links. Use them or the same ones from DevTeam site.
iPhone 3G + NO UNLOCK: If you do not need unlock, you are using your iPhone with one carrier or you hae factory unlcoked iPhone, just restore or upgrade to 2.2.1 using iTunes and use QuickPwn to jailbreak and add Cydia and Installer.
iPhone 3G + UNLOCK: you need to preserve current baseband software. Preserving the baseband will ensure that you can still use “yellowsn0w” the iPhone 3G unlock application. To upgrade your phone to 2.2.1 and preserve the state of the baseband you need to create a custom .ipsw with PwnageTool. This custom .ipsw will not contain the baseband update but of course will still allow all the cool new stuff from 2.2.1. PwnageTool is only available for Mac OS X.
DevTeam updated yellowsn0w to version 0.9.7 to work with modified (!!!) firmware 2.2.1, in which you preserve old baseband from firmware 2.2.
DevTeam says that 2.2 update SHOULD NOT be applied using iTunes if you want the chance of a soft-unlock in the near future. Use new version of PwnageTool (not avaliable yet, but will be soon).
Some fact:
The 2.2 firmware for 3G contains a baseband update for the 3G iPhone
The 2.2 firmware for 2G (1st gen iPhones) doesn’t contain a baseband update and the baseband is still at 04.05.04
Pwnage technique (and therefore the Jailbreak) isn’t affected, but PwnageTool and QuickPwn do not support this release as yet, so DO NOT install 2.2 using iTunes as you will lose your jailbreak
If you apply this update and you previously relied on PwnageTool or QuickPwn to activate your phone, it may become temporarily deactivated and unusable (until we release the new version of PwnageTool or QuickPwn).
PwnageTool and QuickPwn updates will be released as soon as possible that will allow a safe update path to 2.2 the release of these updates is inevitable but not imminent, we are creating the modifications right now and we need to put the new software through the usual testing process.
If you apply this update and you have third-party (non AppStore) applications from Cydia and Installer that you rely on they will stop working.
2G (1st gen) iPhone users who cannot wait for the new PwnageTool or QuickPwn can safely “Update” to 2.2 using iTunes, this will preserve the existing activation. However “restoring” to 2.2 using iTunes will return the iPhone to the unactivated state. If you are in any doubt just wait. NB: This works 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 locked iPhone 3G: early reports suggest that the 2.2 update disables the functionality of these devices.
