Hi,
I'm sad to find that the GMaps JS Data API does not appear to be
supported in Opera desktop 10.00 or Opera Mobile 9.7 beta. An
"Unsupported browser. Continue at your own risk." alert is thrown by
the gdata JS code.
Its a shame as OpneLayers mapping works quite well on WindowsMobile +
Opera Mobile 9.7.
I had hoped to load routes created on my site here
http://wtp2.appspot.com/wheresthepath.htm
to a mobile page here
http://wtp2.appspot.com/mobile/mobile.htm
(which after a bit of tweaking I have managed to code JS AuthSub login
for)
