iPod mini - software update >1.4 results in reset cycle

My wife's iPod mini has finally been brought in from the car for updating and syncing.

Previously it was running 1.3 and was running fine. Naturally it's been a while since it had it's software updated and tonight, iTunes prompted me to update to 1.4.1

The update went fine and the iPod went through the usual upgrade steps (usual = the same as my iPod).

Unfortunately the mini now goes through the usual Apple startup screen displays the menu for around 2 seconds and then resets. This cycle continues ad infinitum.

I can get the iPod to enter "Disk Mode" and have tried a "Restore" using iTunes 7.1.1.5 but to no avail. Whenever I try to use the iPod in normal mode, the reset cycle continues.

Needless to say She-who-must-be-obeyed is not best pleased that her favourite in car entertainment is now not functioning as it should so I'm in the dog house.

As a stopgap, does anyone know where I can get the old version of software so I can at least get a working ipod again?

Thanks for your time and trouble,

--A.
