Sorry if this is the wrong group but my Google mojo has left me and I
don't get the answer I need in the many Nokia and N800 forums about
this.

When I'm not in range of Wi_fi I use my mobile phone for data transfer
for my N800 but don't want to use half of it downloading adverts. Can
anyone recommend a decent adblocker or give some tips on stopping them
from getting near my machine like something along the lines of a HOSTS
file? Any help or pointers appreciated.

Cheers.
