Could someone who has a working T-Mobile sim in an unlocked Iphone 3G or 3GS post what the standard settings are for Web N Walk so that I can go on the internet. I have phoned T-Mobile but they told me that the phone is not supported. Any help would be really appreciated. I did a search on google but saw some conflicting advice so I wanted to hear from someone in the UK who currently has no problems.

If you need to find the info again, you can go to the T-Mobile User Manuals page (T-Mobile - Help & Support), pick a reasonably up-to-date phone, open the manual and the section that says Connecting to the Internet and look for the link saying Set up a GPRS data connection for the Internet
That will list the APN, Username and Password you need.
(The MMS Settings are under Picture Messaging/Set up a GPRS data connection for picture messaging)
