    According to Apple’s support forums in the last few weeks problems about OS4 upgrading, the iPhone will no longer pick up the presence of Wi-Fi networks at all. Reverting to the old iPhone operating system does not resolve the problem, nor does resetting the phone to factory-original status. Forum posters posit that the upgrade in some way has “fried” the Wi-Fi chip in the phone, leaving it unfixable via software.

    i havent update my iphone jet but i just wanted to know if this can be true???, i readed some post here about the ios4 update process and result posted by users however nothing about this issue..

    Apple support also said ios4.0.1 will be released in about 26 minutes.

    They also said iPod touch 5 will have 512 mb ram

    My iPod crashed while it was just doing nothing. While restarting, the screen was spammed with errors (verbose mode) and all of these errors were related to the WiFi chip not being detected. Inside the Settings app, it said No Wifi and it was grayed out and could not be clicked. I tried restoring a couple times but it didn't work. Then I tried a DFU restore to 3.1.2 and it still didn't work. I upgraded to 4.0 and left my iPod off for a while. A few hours later, I came back, turned it on and the WiFi somehow started to magically work.

    I receive the "No Wifi" issue on my 3G, happened at about beta 3. After some investigating my wifi chip is either fried or NVRAM table is corrupt (could be fixed on 2G with swifi), restoring does not fix it.

    Radio still shows the iPhone as having a WiFi mac address, yet settings reports "N/A"
