ah...yes that mass "visitor" issue didn't help eh?
there must be someone in the "Mod Squad" or higher up the food chain or an ip -phreak around here who can help you out. I bet it is seeing your ip address as part of a block that has been banned (due to the "visitors)

hm...

In fact...that will be 99% most likely what has happened .

Which in turn may have possibly some effect on your n900 from that other thread ..it isn't a certainty ...but the possibility of side effects from a restricted and altered ip access may indeed have repercussions ...
(though slim and remote a possibility it is)

Also ...
You have an n8x0 don't you?
If memory serves...
So it isn't like you are totally out of the maemo scene due to having no device.
the n8x0s more fun to play with anyway...
