Apple has posted a new support document outlining the steps users can take to try and fix specific Wi-Fi or Bluetooth issues on the iPhone or iPod touch. According to the article “Unable to use Wi-Fi or Bluetooth with iPhone or iPod touch because there’s no address listed for the device,” symptoms of the issue may include a greyed out Wi-Fi or Bluetooth icon, a lack of an address for either or both of the protocols, the appearance of a Wi-Fi signal but no ability to connect to online services, and the inability to pair with a Bluetooth device.
Apple lists three steps for fixing these problems, telling users to try resetting network settings, erasing all content and settings, and restoring the software. If none of those three methods work, Apple says the device may need repairs.
A number of users have reported problems with Wi-Fi and or Bluetooth following the installation of iPhone OS 3.0, however, it is unclear how many users are dealing with the specific issues outlined in this document..
