The Ultrasn0w 2.1 is just few hours away from release which will unlock all the basebands for iPhone 3G and iPhone 3Gs and seems the unlock for iPhone 4 will take some time for base band/Modem firmware 0.1.59.00 and this unlock will also work for modem firmware/ baseband 05.15.04 and 05.14.02 as well so folks have your breathe for some more hours..This release version will be Ultrasn0w 1.2 which will be used to unlock iPhone 3Gs an iphone 3G only.
This news came as a confirmation from a tweet from MucsleNerd who is the key member in developing this tool..

How to unlock iPhone 4 running on iOS 4.2.1 for baseband 0.1.59.00 and 02.10. Ultrasn0w 1.2 ?
If you are a Iphone users you have to wait for next release.
But This release will make happy to all the iPhone 3G and iPhone 3Gs users who mistakely or upgraded via itunes to latest iOS 4.2.1 or iOS 4.1 which will automatically preserve your baseband and if you ipgraded it in iPhone 4 you will still need to wait for a while becaue the unlock for modem firmware/baseband 02.10.04 is still in developing stage and seems soon the release will be made…
Here was the tweet he made some days ago in in Twitter for the development of ultrasnow:
@MuscleNerd: Good progress today…everything is on track for updated ultrasn0w by Sunday/Funday at the latest (longer for iPhone4!)
And here is what he replied to one of his friends

@MuscleNerd: Finally got ultrasn0w working fully on 4.2.1. Apple inadvertently(!) broke ultrasn0w via aggressive compiler optimization
This means it will be used to unlock all the baseband or modem firmware for iphone 3G and iPhone

same here too 4.1 with 5.14.02. done some reading, i think it doesnt support this but the workround is: "It turns out that the very first iPad firmware 3.2.2 has baseband version 06.15.00 still vulnerable to AT+XAPP. The iPad baseband is built for the exact same baseband chip as the iPhone3G/3GS — they’re fully compatible! " heres how to do it.. http://blog.iphone-dev.org/ if you dont hav Mac (like me) you have to wait for new Redsn0w which should be out any 'minute'..
