I bought a new Nokia E71-2 yesterday, popped in my SIM from T-mobile and it was working like a charm. Even w/out 3G the web was pretty good w/ EDGE or my wifi in my apartment. then this morning T-mobile automatically sent me a message with configuration settings. Foolishly, I saved it as directed and now it tells me that I need to subscribe to a data plan. It worked fine before! I could go to any website I wanted to (I have an "unlimited web for phones $9.99 service that I used on my previous nokia flip-phone). How do I roll back the settings to where they were? thanks!
