It should be:
set useragent=<NEW_UA>
for example:
set useragent=iphone-3
You don't even need to restart Firefox. Just pres `:' to open
pentadactyl prompt and type `source ~/.pentadactylrc'. You can also
execute `set useragent=...' command right in the prompt but it will be
forgotten after Firefox restart.
