Just tried with my W880i too. Exactly same result. Both contract phones.

I have not purchased a plan as yet (£10 for 1Gb) .. was going to try to see if it worked first before buying a plan( and therefore be charged £2 per Meg .. £2 quid is cheaper than paying £10 ! to find it don’t work).

It seems to throw the “ cannot connect to internet “mesasage a bit too quick for me to think that it’s the bandwith that’s the issue ..

When starting the DUN for the 1st time the N800 asks if it can use the phone as a modem.. i click yes.. then allow always.

I have tried to connect to the phone before trying to connect to internet, I get the " do you want to start the remote control " message..if I select desktop then that works great .. .. browsing the N800 via the controls of the phone .

Question 1.. when you buy a plan do you receive a text sim update that adds something extra to the phone menu ?

Question 2 .. are you running Diablo ?

For the sakes of experimentation I will phone 3 now and take a 1 month plan and report back.
