    My iPhone 3G stopped seeing any WiFi networks several months ago and has never worked once, except for about 5 seconds after I restored it as a new phone. It didn't even connect that time either, It just found my network. It worked perfectly until sometime around the 3.0 update (however I am not blaming 3.0, it might be a coincidence). The iPod Touch, iMac, MBP, Dell laptop, 2 Toshiba laptops, and my PS3 can all see it and connect to it fine, so my setup is definitely not the problem. It suddenly stopped working one day and has never connected again to any network. Even public ones (Starbucks, library, etc.). It's a pain to have so many apps that don't function completely without WiFi.

    Another thread on the issue that has 85 pages of replies (Apple forums)

    On the Apple forums, someone said that putting your iPhone inside a plastic bag in a freezer helps because there are micro scratches or something on the soldering that mess up the connection. Many people tried it on that thread and it apparently worked. I don't have a warranty anyway, so it isn't voiding anything that isn't already voided.

    My question:
    Has anyone had this issue and fixed it?
    Has anyone tried the freezing method?
    If you haven't tried it, do you think it will work?

    Well, people here are pretty helpful, so I think you can take the lack of replies as a :confused: or a :eek:

    Sounds to me like your wifi aerial is dead, so I guess you have nothing to lose by freezing it - err, except the rest of the phone's functions of course!!!!! If you do it, I'd advise you to power it off, then after you take it out of the freezer, leave it a few hours at room temperature before powering it back on, otherwise condensation will get everywhere in the phone and probably kill it altogether.

    Ok, thanks a lot. I'll probably try it later.

    I am having the same issue.
    My iphone 3G couldn't find any WIFI network a couple weeks after 3.0 upgrade. Not sure if it is software related. All the resetting, restoring won't help at all. I called Apple and they suggested I pay $199 to replace it becasue it is out-of-warranty.

    I tried the refrigerator trick. It did come back up for a few seconds but died again. It doesn't hurt to try. Just make sure put it into a sealed bag or box. After you take it out, wait a few hours till it warms up to the room temperature before you open the sealed bag/box.

    After 3.1.2 upgrade, My iphone WIFI comes back to work occasionally. It finds WIFI sometimes, it was able to connect to the network for a few seconds or minutes, then it drops.

    I coundn't find any solution out there beside paying $199 for a new one.

    After 3.1.2, mine is still not working at all. I have tried numerous restores, network setting resets, etc. all to no avail. Seriously? Now I have an out-of-warranty iPhone with no WiFi at all.

    Oh, and I just found out that my Bluetooth isn't working either. What's next, my 3G? :mad:

    So many people have reported the same problem with the 3G. I have a 1G iPod Touch that works flawlessly and my friend's 2G worked great as well. I can't use half the apps I have now! :mad:

    Don't return your phone for a new one. I did this twice already under warranty and it didn't fix the problem. :mad:
