Apple released iPhone firmware 2.2.1 yesterday which included minor bug fixes and improvements as per the release notes.
However, it looks like there was another reason for releasing the latest firmware. The Dev Team who had warned against updating to the latest firmware has confirmed that iPhone firmware 2.2.1 breaks the "injection hole" that they had used in their application yellowsn0w to modify the firmware which had helped to successfully unlock iPhone 3G.
MuscleNerd, a member of the iPhone Dev Team who had released World's Software method to unlock iPhone 3G on 1st Jan 2009 had this to say over Twitter: for *jailbreak* purposes 2.2.1 is fine for all including ipt2g. But it BREAKS the yellowsn0w soft *unlock* for iPhone 3G it's not surprising that they fixed injection hole for yellowsn0w, it is surprising to see a "silent" update the iPhone 2G baseband is untouched .. I *think* they've stopped all development of it :) last update for it was 8 months ago
He has also broadcasted a video on Qik to explain what it means if you upgrade to iPhone firmware 2.2.1.
As we had reported yesterday, iPhone firmware 2.2.1 also updates the baseband (modem firmware) from 02.28.00 to 02.30.03 thus breaking the software method to unlock iPhone 3G.
Options if you have already Upgraded to iPhone Firmware 2.2.1:
So if you have upgraded your jailbroken and unlocked iPhone to firmware 2.2.1 (or just about a new iPhone which came pre-installed with firmware 2.2.1), then you are left with the following options depending on your version of the iPhone:
1st gen iPhone: Since the update does not touch the baseband of the 1st gen iPhone your unlock will remain in place. However to jailbreak your 1st gen iPhone you will need to wait for the dev team to release updated versions of PwnageTool and QuickPwn tools which will let you jailbreak your 1st gen iPhone running firmware 2.2.1.
iPhone 3G: The Dev team should soon release updated versions of their PwnageTool and QuickPwn tools to jailbreak your iPhone 3G running firmware 2.2.1. But since the latest firmware updates iPhone 3G's baseband to 02.30.03, you will not be able to unlock it. You will need to wait for some time for the Dev team can unlock baseband 02.30.03.
Options if you have NOT Upgraded to iPhone Firmware 2.2.1:
In case you have jailbroken and/or unlocked your iPhone but haven't upgraded to the latest firmware then then your options based on the version of your iPhone are mentioned below:
1st Gen iPhone:
If you do not care about jailbreaking but only worried about unlocking your 1st gen iPhone then you can go ahead and update your 1st gen iPhone as the update does not touch the baseband of the 1st gen iPhone so your unlock will remain in place.
If you care about jailbreaking then you need to wait for the dev team to release updated versions of PwnageTool and QuickPwn tools which will let you jailbreak your 1st gen iPhone running firmware 2.2.1.
iPhone 3G:
Please avoid updating your iPhone with the latest firmware until the iPhone Dev Team have not released the latest version of PwnageTool. The latest version of PwnageTool for iPhone firmware 2.2.1 will help you to safely upgrade only the iPhone firmware to 2.2.1 and not the modem firmware.
Lets hope most of you had read our post yesterday or read this one before updating your iPhone with the latest firmware.
The cat and mouse game between Apple and the dev team continues. Let us know your thoughts in the comments below.
Update:
These comments by MuscleNerd over at Dev Team's blog should clarify things further, we have also updated the post accordingly:
Since this update doesn't touch the iPhone 2G baseband, your unlock patch will remain in place. So for iPhone 2G owners who care only about keeping their unlock -- not about jailbreaking -- you can take this update right now.

I completely and totally screwed up my iPhone – can't even downgrade it to 2.2. or restore the 2.2.1 firmware with 02.28.00 baseband. So I'm stuck with the 02.30.03 baseband. Ew.
So is there any news if the Dev Team is working on updating YellowSn0w so it will work with firmware 2.2.1, baseband 2.30.03.?
Please help!
heyy i purchased an iphone 3g with the 2.2.1 firmware. Its locked to rogers while im with fido. So im just waiting for the new unlock to come out…would any body have an estimated guess of when this unlock is going to be released?
I updated my iphone 3g from 2.2 to 2.2.1 from itunes, after updating, the phone refuses to start up, it's displaying a usb plug pointed to itunes on the screen of my iphone. I dont know what to do. pls help me. I love my iphone so much that i dont want to lose. pls help me. Thanks
I upgraded and unlocked my iPhone 2g to firmware 2.2.1. Now everything works fine but the rightone is very low and during any conversation I can't hear the other side due to low volume . I tried the iclarified source in the installer for volume booster application but it doesn't show in the installer. Can any one give me a alternative way or help me fix it.
fuck…im confused
that means i cant unlock my iphone??
iPhone firmware 2.2.1 update consists of the OS update as well as a modem firmware update (02.30.03).
Dev Team's software method to unlock iPhone 3G works only with modem firmware 02.28.00 which was bundled with iPhone firmware 2.2.
So if you want to unlock your iPhone 3G, you should preserve the baseband using PwnageTool which is only available for Macs.
If you have already upgraded to modem firmware 02.30.03 then currently there is no way to unlock your iPhone 3G.
This isn't applicable to 1st gen iPhone, you can use the latest tools to unlock it.
hahahaha.. i just sold yesterday my iphone with 2.2.1 firmware, and 2.30.03 baseband… I have a friend who has this super kung fu software (i forgot what that $hit called) to unlock the phone. I Jailbroken the phone (using that software), worked fine (i can call home), installed those free apps i found over torrent sites, attempted to unlock the phone… seems to worked fine…rebooted again the phone…and BAM !!!
i got my self an i-phone touch..!… it worried me sick…
then..I grab me a shirt, went to the mall and sold the phone/touch to some unsuspecting nerd… told the nerd that it got the latest cydia apps and all those BS sales pitch.. the nerd paid up front…
Got home… called my friend… and yelled at him..!
"you *#@*$* idiot…" i almost got killed by your super kung fu software…
