[Tiny posts on their website]
Tiny Code no longer produces fixes or applications for firmware 1.1.3. We can't say much, but we are working with Apple and with their SDK for the next firmware release and SDK applications and we shouldn't be missed for long. We will no longer update our Installer.app repo for legality reasons and you should see us soon on iTunes.
The side bar also lists "targetting fw 1.1.4 Alpha 2", though we would hope that a planned February release would have progressed beyond Alpha stage by now.
Update: Comments from the Tiny-Code developer:
Yes, Tiny-Code.com was ordered to be removed from operation by Apple, Inc because by releasing firmware versions and stating I had possession of the firmware and SDK was apparently a violation of the Non-Disclosure Agreement I agreed to when I accepted a copy of the SDK and firmware.
The guys that do this sort of thing only prove why Apple is reluctant to release unapproved development kits for it's specialized products like the iPhone and iPod.
