iOS 4.0.2 unjailbreaks your phone, but fixes PDF vulnerability to compensate
The latest 4.0.2 version of Apple's iOS is now available as a hefty 579MB download from iTunes for the iPhone 4, 3GS and 3G, as well as the iPod touch 2G/3G and the iPad. It plugs the leaking PDF view in Safari, which was exploited by JailbreakMe – the web-based solution that allows owners to install Cydia, and subsequently unlock their devices.

The 4.0.2 version of iOS puts an end to these frivolities and closes the loophole, thus sending the jailbreak masterminds back to the drawing board. Interestingly enough, it doesn't fully seal the iPhone 3G. If you use the latest version of Redsn0w, it will still jailbreak the iPhone 3G running iOS 4.0.2 and, since the the default 05.13.04 baseband remains unchanged, you can then unlock it with Ultrasn0w as well. The same steps seem to work on the iPod touch 2G (non-MC version). Follow the links in the source for the detailed instructions.

I thought unlocking your phone was legal now. If so then it sould be illegal for them to send a fix out to prevent you from unlocking your phone.

It is legal but nothing in the law prevents them from unjailbreaking your phone in subsequent updates.
