Shortly after the iphone 4 is officially launched with the latest firmware iOS4, hackers released the tools to jailbreak & unlock the latest firmware on the 3G & 3GS phones. Though the hackers found the exploits during the beta of iOS4 & 3.1.3 firmware they did not disclose is because apple would close them in the main release. Note that 3G & 3GS iphones are supported on iOS4 but not 2G iphones. They updated the following tools:
pwnage tool - to jailbreak the new iOS4 firmware (redsnow should follow)
ultrasn0w tool - to unlock the baseband
The good news is that the updated ultrasnow tool (v0.93) can unlock all the basebands till the latest one (5.13.04). The new firmware updates that baseband (responsible for gsm communication) to the latest one but the latest ultrasnow tool can unlock it so that the phone can be used on other networks. So, even if you accidentally updated your iphone firmware to 3.1.3 version (which also updates the baseband to 5.12.01) which rendered the phone not usable on other networks this latest tools will be your savior. The users with jailbroken phones on 3.1.3 firmware can also use ultrasnow without upgrading to iOS4.
The bad news is that the pwnage tool cannot *yet* jailbreak the 3GS iphones with the new bootroms (iBoot-359.3.2). The iphone week number will help as a thumb rule to find if your 3GS iphone is having old or new bootrom. The 4th and 5th digits of the serial number will tell the week number of the phone. If your iphone week number is <40, then you will definitely have old bootrom. If the week number is >45 then you will definitely have new bootrom. In between, we cannot say for sure. The sure shot method to determine the bootrom is to use some tool like 'usbview' and put the iphone in DFU mode.

unlock of 3G and 3GS
update(5-July): If you have the 3.1.2 SHSH blobs stored (not 3.1.3 shsh blobs), there is a way you can jailbreak the 3GS phone with new firmware. See this tutorial.This tutorial is not yet for the faint hearted. These steps were released for the advanced users as the tool development will take some time.
