Hoppa, I really, really hope that nokia replace your n900. It certainly sounds like you got a 'Friday afternoon model'.

This thread illustrates the bext and worst aspects of this community - from people reading the title and jumping straight to "buy an iphone" (when frankly, your ability to diagnose and problem solve waay outstrips mine!) to people criticising your grammar (I can only excuse them saying they failed to take on board the possibility that English is not your first language) and finally to the helpful people refusing to let go of a problem until it is sorted.

Now if we could just cut to the useful ones without all the rest...

Good luck with Nokia Care.
