[aprssig] Problem with aprs.fi on Palm Pre?

[Ted11]

I'm trying to view aprs.fi information on my Palm Pre.  I get the track, and
I get the menu on the right, but I don't get any base map.  Has anyone else
experienced this, either on the Palm Pre or other smart phones?  I don't
believe there is an APRS app for webOS, so I think I'm stuck with whatever I
can get from the browser, for now.  Any advice or workarounds appreciated.
