haha, theres no trick, it all depends who you speak to on Orange's end, I know this post is a bit anti-orange, but all-in-all they aint as bad as say 3 or t-mobile, so don't feel to downhearted about it.

like i said you need to put your sim in a 3g phone, that way;

if it dont work -> then its orange

if it works -> you know its your n900 and can concentrate on looking at the settings again or re-flashing the device.
