UPDATE : Jailbreaking 2.2 Firmware was made possible again by iPhone Devs and if you want to download custom ipsws, click here or you can download the jailbreaking tools here.

UPDATE : The overall experience is lot smoother and a lot lot snappier (SMS, Safari,…), fewer Crashes and One Word : Well worth it but I still suggest you to hang in there for the 3G Software Unlock which is due (If you need it that is!).

As anticipated, Apple dropped a major iPhone firmware update v2.2. True to the rumored features, Google Maps, Safari, OTA Podcast Downloads, and few other minor feature enhancements are made.

Those using iPhones activated using Unlocking Software (QuickPWN, PWnage) are SERIOUSLY suggested not to hit the update button since it might render your iPhones unusable!

Now for the best part : iPhone Devs are on the brink of a revolutionary 3G Software Unlock release!

What this update does to the BaseBand (from iPhone Devs) :

The 2.2 firmware for 3G contains a baseband updater 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 if you have third-party (non AppStore) applications that you want to use right now

Bottom line : WAIT and don’t say you were not warned!
