Until work on the iPhone OS 3.1 (currently in Beta) is complete and the Cupertino-based company can release the update, Apple has decided to take a stab at one pretty annoying problem the iPhone OS 3.0 brought: the incapacity to use WiFi or Bluetooth on the iPhone or iPod Touch. There are several symptoms attached to this issue:

1. No WiFi or Bluetooth address is listed.
2. You seem to be connected to the web via WiFi, but you cannot browse the web, check your email, or send data over WiFi.
3. The iPhone is not able to pair with your Bluetooth device or accessory.
4. You cannot see any values or entries for IP Address, Subnet Mask, Router, or DNS appear when you tap Settings -> Wi-Fi -> the arrow icon next to the network.


The following products are affected: iPhone, iPod touch, iPhone 3G, iPod touch (2nd generation).

“This can happen if, during the initial setup of the iPhone or iPod touch or after performing a software update or restore using iTunes, no Wi-Fi or Bluetooth address was registered,” explained Apple. To resolve the issue you must sync your device to iTunes and backup all you info; then you must use one of the workaround presented below:

1. Settings -> General -> Reset -> Reset Network Settings
The WiFi or Bluetooth address should be listed now in Settings -> General -> About -> Wi-Fi Address or Bluetooth. Still not working for you? Try the next step then.

2. Settings -> General -> Reset -> Erase All Content and Settings
The WiFi or Bluetooth address should be listed now in Settings -> General -> About -> Wi-Fi Address or Bluetooth. Still not working for you? Try the next step then.

3. Restore the device’s software using iTunes -> sync all your previous settings -> check to see whether the WiFi or Bluetooth address is displayed (Settings -> General -> About -> Wi-Fi Address or Bluetooth). Still not working for you? Try the next step then.

4. You tried all the steps presented above and none of them work? There may be a problem with the device itself, problem that you cannot solve yourself. You may need to take it in for repairs. See this Apple Support article for details.

In related news, Apple recently announced that the iPhone 3G S may be affected by overheating issues. There are certain situations that might trigger the Temperature warning message to appear. Like for example if you leave your iPhone in your car, it is a hot day, and the sunlight hits your car directly. Or when you leave your iPhone exposed to direct sunlight for large amounts of time. Even if you are in a shaded location, using resource-hungry apps on a hot day for a longer period of time might trigger the warning message as well.

What you should do, as advised by Apple, is use the device in places where the temperature is between 32º to 95º F or 0º and 35º C and store the device in places where the temperature is between -4º to 113º F or -20º and 45º. Keep in mind that using the device in very low or very high temperatures may cause the iPhone 3G S to stop functioning or may shorten battery life.
