Short answer:
NO !!
Long answer:
You can search for the non-hosted version of Inten/DE/NoWhere,
and flash your PDA with it, but that would void your warranty,
has nothing in common with "Amiga" except the name, and there is
allmost no SW to run it ....
A quick search if there is an UAE-port for QTopia/Linux might
turn out something a little bit more usefull.
