iPhone 1.1.3 jailbreak released

Although initial reports stated the 1.1.3 jailbreak for the iPhone would not be released until the SDK this February, I awoke this morning to find that it is now available to both Mac user's and PC users.  Although initial reports of unlocked phones suggest that the phones remain unlocked, it would be smart to wait for a more definite conclusion on the matter.  

Update:  I personally haven't been able to update and a friend of mine with an unlocked iPhone is stuck locked again, so I must stress use at your own risk.
