check your warranty and if you have a warranty left on it restore the phone and take it to apple they will give you a new phone. other than that i dont know if there is a fix for it.

To determine that it is a hardware problem do the freezer trick: Put the iPhone in a ziplock bad and then put that in a ziplock back (to prevent condensation, also remove as much air as you can) and put in the freezer for 10 minutes or so. If you have wifi for a bit after that, then it is definitely hardware. If not, it could still be hardware, but do a restore in DFU mode and see if it changes (you'll need to restore anyway to take it to Apple).

iphone 3g-WIFI problem

I had an unlocked iPhone 3G. While charging the iPhone, it started getting hot.
WiFi deteriorated progressively after that over the next couple of weeks - dropped connections, then unable to detect WiFi routers.

I took it to the Apple store (after restoring the iPhone to a standard state - no longer unlocked.
I used a friend's AT&T SIM, but removed the SIM when bringing it to the Apple store.
The service rep looked at the phone and noted I was six weeks past my warranty, But he said he would speak with his supervisor and then replaced the iPhone for free!
