Soon after the release of iOS 4.1 a vulnerability was found - this vulnerability is currently being worked on and hopefully a jailbreak will be developed soon.
No mention of a corresponding unlock has ever been mentioned and, based on comments by a prominent hacker, there is a possibility that you will first need to be on a firmware version lower than 4.1 before upgrading to 4.1 ( probably via Pwnage Tool ) in order to preserve the unlock that exists in the lower version firmware. This way you can be on 4.1 with an unlocked iPhone.
It all probably sounds confusing but the bottom line is DO NOT upgrade to 4.1, even if you are on 4.0.2 firmware where there this is not a jailbreak for the 3GS iPhones.
Furthermore, if you "accidentally" ( or deliberately ) upgrade your firmware to a higher version ( e.g. 4.1 ) that does not have an unlock, downgrading to a lower version ( which, by the way, cannot be done for out of the box 3GS and iPhone 4 models ) WILL NOT make your iPhone unlockable. This is because even though you may have downgraded to a firmware version that can be jailbroken, the component of the firmware that is unlocked DOES NOT get downgraded - it stays at the higher version and is not unlockable. This is why you do not want to go to 4.1 if you rely on an unlock.

New firmware 4.1 coming out Today! Sept. 8
Currently the highest version firmware for iPhone is 4.0.2 - it cannot be jailbroken.
Next week you'll see 4.1 pop up when you plug your iPhone into iTunes. This version is currently not jailbreakable and all people who like their iPhone jailbroken, and unlocked, should avoid upgrading your iPhone. Although I hope that some hacker has the jailbreak for 4.1 and is just waiting to release it ( NOTE : THIS HAS BEEN CONFIRMED ). Note, however, that no mention of an unlock has been made.
Soon I will be posting a short tuturial on how to determine if your 3GS or iPhone 4 can be downgraded to a jailbreakable version of firmware. Yes, this is possible but you would've had to have chosen "Make my life easier" in Cydia ( I take this precaution with all iPhones that I jailbreak ). More on this later.

New firmware 4.0.2 is out ... it CANNOT be jailbroken
Just a quick note to let you know that 4.0.2 firmware was released yesterday. Note that while this firmeare version DOES fix a serious security risk ( the one that the current jailbreak utilizes ) it is not currently jailbreakable.
My suggestion to those jailbroken on 4.0 or 4.0.1 firmware is to NOT upgrade to 4.0.2 but to go into Cydia, search for saurik's "PDF Patch", and install it. This will ensure that :
1) Your iPhone will still be running jailbreakable firmware ( you never know when you need to re-install 4.0 or 4.02 and require a re-jailbreak ), and
2) Your iPhone will be secure against any malicious uses of this firmware vulnerability
That's it for now.

New jailbreak for 4.x firmware!
As of this afternoon there is now a jailbreak to handle all iPhone models on 3.x firmware and higher.
I have jailbroken ( but not unlocked, that's coming soon ) my iPhone 4 without issue - some people are reporting Facetime problems.
I have jailbroken and unlocked my 3GS running 4.0.1 firmware without issue.
For now, I'd say hold off for 24 hours and let the issues, and solutions, come out. A quick update for the jailbreak will probably be published.
However, I'd say that if you're feeling brave and have a 3GS on 4.x firmware, go ahead and jailbreak and unlock. Feel free to contact me if you'd like me to do this for you.
I'll post an update when/if an update comes out that fixes any issues.
UPDATE : All issues ( Facetime and MMS ) have been sorted out now, I think that it's safe to jailbreak and unlock now. Note, though, that there is still not an unlock for the iPhone 4. It is currently undergoing some final testing, then it'll be released. However, for the 3GS ... we're ready to go!
UPDATE : It appears as if the unlock for the iPhone 4 will be released in 48 hours ( it's 10:35 PM MST right now ).

Explanation of jailbreak for 3GS iPhones on iOS 4.0
There is a way to have a jailbroken 3GS running iOS 4.0. However, there are certain conditions that must exist :
If your 3GS meets these requirements then you can safely go to 4.0. Note, though, that this upgrade process WILL wipe your iPhone clean so make sure to sync your 3GS before going this route.
My 3GS meets these requirements but I have not yet gone to iOS 4.0 ... though I REALLY want to go there. The reason? MANY Cydia apps do not yet work on iOS 4.0. I use several Cydia apps and don't want to do without them so I will not be going to iOS until "my faves" are good for iOS 4.0 ... another consideration before jumping to iOS 4.0.
- 3GS must be activated
- 3GS must be on a lower firmware version than iOS 4.0 and must be jailbroken, but not with Spirit
- 3GS must not have the new bootrom
If your 3GS meets these requirements then you can safely go to 4.0. Note, though, that this upgrade process WILL wipe your iPhone clean so make sure to sync your 3GS before going this route.

Upcoming unlock for stock 3.1.3 firmware, it's here now!
iOS 4.0 firmware was released today for your iPhones. Soon after came an updated ultrasn0w unlock for all existing basebands : 04.26.08, 05.11.07, 05.12.01, and 05.13.04
Thus, all those with iPhones stuck on 3.1.3 firmware can now have their iPhones unlocked. Note, however, that there is NOT a jailbreak for the new 4.0 firmware. If you are looking to unlock your iPhone do not upgrade to 4.0. An unlock will some within days, in my opinion, so it's not too serious painful of a wait, just hang on.
UPDATE : There are now jailbreaks for 3G iPhones on iOS 4.0 firmware. For 3GS iPhones on iOS 4.0 firmware, nothing yet ( the only way is to start with a jailbroken 3GS on a firmware version lower than 4.0, then to 4.0 ). Note however, that for the 3GS, this jailbreak is only for 3GS models that have the old bootrom ( see my post "3GS bootrom issue" for an explanation ).

Upcoming unlock/jailbreak for 3.1.3 and 4.0
With the release date of iPhone firmware 4.0 as June 21st this gives everyone a better idea of when an unlock will be available ... soon!
Typically when firmware is released to the public a couple of days pass then the jailbreak and unlock software is released to everyone. So this would give us a day or so after June 21st until "Happy Day". iPhone hacker @MuscleNerd, part of the Dev-Team, has announced that unlocks for 3.1.3 AND 4.0 firmware will be released. This means that you will not have to upgrade to 4.0 in order to enjoy an unlocked iPhone. Those who "accidentally" upgraded to 3.1.3 can choose to stay with that version for your unlock or upgrade to 4.0 ( it has some pretty cool features so it's worth upgrading, in my opinion ).
However, I'd caution everyone on 3.1.3 to hold off on upgrading to 4.0 until we hear from the hacking world to ensure that you have the best options for unlocking.
That's it for now.
