I have recently got a P800 on T-mobile in the UK. Everything works OK, sync'd with my PC, set voice tags etc, but I cannot get the internet.

T-mobile have sent me text messages which automatically input the settings and I have received similar from the Sony Ericsson website. When I click on the internet icon I get the bouncing ball but for anything from there on, I get a blue Information box at the bottom of the screen saying "unknown error". I know its not much to go on but anyone seen this before or might have a clue as to how to fix this? Thanks.
