I finally solved it!

The script works for the new 8120 (THANK YOU!!!!!)
And in OSX 10.5.2, some of the names for boxes etc. are different. Here's what worked for Tim In Italy

Phone #: ibox.tim.it
User name: guest
password: guest

I did have the problem that some described early in the threat about no bars on "receiving" but the problem is one of signal strength, which here is dodgey, but workable.

Thank you thank you thank you!
