I recently got a new iPhone 3G from apple because my previous one was misfunctioning and after the first day of using the new iPhone the Wi-Fi no longer works. No networks are picked up, the Wi-Fi option is greyed out.

Has anyone else had this problem? Any steps I can take to resolve it before taking it back to apple?

Try to do a restore from a new phone and see if that helps. That will be the first thing they do too.

Do you mean the option under Setting for Wi-Fi is greyed out? That can't be good,

I'd recommend a restore to factory settings unless someone else has a better idea. That's what Apple would eventually tell you to do anyway before you send it in to them.

I did that last night, such a pain, but even that didn't solve it. It worked on the first day, then greyed out for a week, then had Wi-Fi for 2 days before it greyed out again.

Sounds like it would be a great time to put the Apple Care into effect and just get a new phone. Does it turn grey after some settings you mess with or anything, or does it just no allow you to turn it off/on anymore?

Yeah I think i'll just have to do that, this will be my 3rd iPhone in 4 months, none of it my fault!

The Wi-Fi is completely inaccessible, just says No Wi-Fi. I can't think of what else to try!

Time for an appointment at the Genius Bar then. Best of luck, make sure you post what happens!

Had the same problem. Restoring phone did no good. I had to reset my router. My a firmware upgrade needs to be done (to the router).

Goto a Burger King parking lot and see if your Wifi works, they have free Wifi... This will show if its your iPhone or your router... Always eliminate first

Went to the Genius bar, it was swapped, no questions asked really. I asked if it was common and he said "it was, there was a faulty batch", don't waste time trying to repair, just get it swapped if it happens to you.
