Another news directly from Toc2rta:
So its offical we have released the tiff exploit code. You can navigate in safari to http://jailbreak.toc2rta.com on your Itouch or Iphone 1.1.1. It will crash your Safari but then you will be able to browse the file system with full read/write access. This is only for people who understand what they are doing. You will need IPHUC and some knowledge of how to put/get files.

Check back later for a full breakdown of how the tiff works and what the future holds for Toc2rta and the Itouch & Iphone.
Exploit by Niacin and Dre.
