iPhone Firmware 2.2 is Out. Jailbreakers Should Not Update!

The rumor was right… Apple did release firmware 2.2 last night and for once, it seems that we have some useful features added:

Enhancements to Maps:

  • Google Street View
  • public transit and walking directions
  • display address of dropped pins
  • share location via email

Enhancements to Mail

  • resolve isolated issues with scheduled fetching of email
  • improved formatting of wide HTML email

Other Enhancements

  • Improved stability and performance of Safari
  • Podcasts are now available for download in the iTunes application (over Wi-Fi and cellular networks)
  • Decrease in call set-up failures and call drops
  • Improved sound quality of visual voicemail messages
  • Pressing the Home button from any Home screen takes you the first Home screen
  • Preference to turn on/off keyboard auto-correction

Apparently, iPod Touch users don’t get the Google Maps upgrade that includes the addition of Street View as well as public transit and walking directions.

Like they did earlier this week, the Dev Team warns us about updating the iPhone using iTunes.

So, as anticipated our friends the misfits have recently released the long awaited 2.2 update. We can confirm that this update SHOULD NOT be applied using iTunes if you want the chance of a soft-unlock in the near future.

If you want to keep that option of a ‘soft-unlock in the near future’ available but you want the new features of 2.2, you will be able to update to 2.2 using a PwnageTool created custom ipsw file that disables the baseband update. You will be able to do this using an updated version of PwnageTool that will be released sometime soon.

Some facts –

  • 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
  • We believe that our 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  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 is a method that we have always advised against. Early reports suggest that the 2.2 update disables the functionality of these devices. The techniques used were always unreliable and we are surprised that they have lasted this long.
  • We are not working on the 2nd generation iPod touch at the moment, so we cannot comment on what the the 2.2 software update may do to this specific model

So, as always, if you are in any doubt whatsoever please delay the install of this firmware on any of your devices until we have investigated the release in more detail. Watch this space 😉

Also, iTunes 8.0.2 is out now. I doubt this will make much difference either way, but ask yourself, why bother. Just because a new version is out doesn’t mean you want it. I would hold off on this also.

iPhone Firmware 2.2 and iTunes 8.0.2 are both available from the downloads section of our blog.
