Dev Team has found an exploit for iOS 4.1

When the iPhone 4 and iOS 4.0 was released, the Dev Team was able to relatively easily develop a browser-based jailbreak using JailbreakMe.com. The jailbreak made use of an vulnerability in the way that Mobile Safari handled PDF documents.

Now, just hours after the official iOS 4.1 ipsw was posted to Apple's servers, the Dev Team has discovered a bootrom exploit that will used in the iOS 4.1 jailbreak. The Dev Team's Musclenerd tweeted, "Crazy timing that @pod2g got latest exploit just as 4.1 went public (lots of work left…keep away from 4.1 for now!)."

According to Redmond Pie, this exploit won't be something that Apple will be able to patch as quickly as the previous PDF exploit:

Also, the best thing about a low-level bootrom exploit is that Apple wont be able to patch it simply by releasing a new firmware update. Instead, it will require Apple to release a revised hardware version of iPhone 4, iPhone 3GS, iPad and the iPod touches with new bootroms in order to patch the bootrom exploit.

This is good news for iPhone 4 users that want the fixes included in the iOS 4.1 update (proximity sensor, Bluetooth connection issues), while at the same time providing access to the wealth of "underground apps" and customizations that can be had with unauthorized app stores like Cydia.

You'll just have to be patient as the Dev Team works its magic to complete work on the iOS 4.1 jailbreak.

It would be more accurate for the article to have reported

"Now, just hours after the official iOS 4.1 ipsw was posted to Apple's servers, the Dev Team has released the bootrom exploit they have been aware of for many months, but which they chose not to make public in order to maximise the length of time it would allow newly manufactured Apple iDevices to be jailbroken."

Ways of jailbreaking aren't easy to come by, each is precious, and must be released wisely otherwise Apple will block them all quite quickly, therefore the reason this has been held back until 4.1 is final.

Are you calling Musclenerd/the Dev Team liars? ;)

Also, the exploit has NOT been released. They specifically said that there is much more work to be done and releasing it now before the jailbreak is ready would only serve to allow Apple to block it sooned with a hardware revision. As it is (private), they can share it with anyone they believe could do something good with it, so it will remain that way unless some trusted idiot leaks it or discovers it on their own without keeping it close to their chest.
