The Dev Team has released PwnageTool 4.0 which jailbreaks and unlocks the iPhone 3G and 3Gs with the old bootrom as well as the iPod Touch 2nd gen, as long as you didn't use the Spirit jb.

First, know that the iPhone 2G, the iPod Touch (first-gen) and the iPod Touch (3rd-gen) are not supported. Also know that this does not work with the developer versions iOS4. It must be the official release that was made available on Monday.

There are many variables to keep in mind when running PwnageTool 4.0. They are important, so here they are:

If you are using a 3Gs, PwnageTool will only work on previously jailbroken phones with the old bootrom, and without spirit jb.  If your 3GS has the new bootrom, then it will not work with PwnageTool 4.0.

Those of you with a 3G also have some things to keep in mind. If you have a jailbroken iPhone running 3.1.2, again, without the Spirit jailbreak, you should create the ipsw with PwnageTool 4.0 and restore from recovery or DFU mode.

If your 3G has not been jailbroken, you should restore using a PwnageTool 4.0 ipsw using DFU mode.

If your iPhone 3G is jailbroken running 3.1.3 the Dev Team warns that it is "very possible" that it can fail from recovery mode. In this event, you must restore using DFU mode. When you go into DFU mode, you have to do it using PwnageTool.

The latest redsn0w, which was released Monday, can also be used as an alternative for those with a 3G or second-gen iPod Touch. Keep in mind that it is not compatible with the 3Gs.

If you are using an iPod Touch, the first thing to know is that this is only compatible with the second-gen models. Again, if you have a touch that is already jailbroken (without Spirit) you can restore with recovery mode. The iPod Touch also supports redsn0w.

Start here. These are the official releases from the Dev Team themselves:
