More iPhone OS 2.2 Problems and Fixes

Users continue to note a series of issues with the iPhone OS 2.2 update.

Weak or non-existent signal As has been with the case with virtually ever iPhone OS update, some users are reporting a degradation of signal after the release of OS 2.2.

One iPhone Atlas reader writes:

"I recently updated my iphone firmware from 2.1 to 2.2 and since then i have no signal from my local service provider(not 3G signal). I experienced no signal problem with the 2.1 firmware."

Another reader adds:

"Since updating yesterday, I have had serious cell connectivity issues. The phone is constantly 'Searching' for cell service in areas where it was not a problem before yesterday."

It appears that, in some cases, turning off location services can boost signal strength under iPhone OS 2.2. For other potential signal-boosting procedures, see our previous coverage.

The most reliable indicator of actual signal strength is the iPhones dB meter, which can be accessed in field test mode. Dial *3001#12345#* then press ?Call.? A dB reading below 50 generally indicates good strength.

Missing applications Some users have reported sudden disappearance of iPhone applications after the update -- even those that ship by default with the device and cannot be voluntarily deleted.

One reader writes:

"Today all of a sudden I don't have Safari or Camera. I did a sync and they're not there. Then a reset and nothing. Then synced again after the reset and nothing. Big bummer since I use Safari all the time. I'm figuring it has to be a software issue. I thought I'd throw it out there in case others are experiencing the same."

If you are experiencing a similar issue, please let us know.

Failed installation Some users are unable to apply the iPhone OS 2.2 update at all, with the installation process failing partway through. In some cases, the phone may become stuck in recovery mode, typified by the image of a USB cable pointing at an iTunes logo.

If you are experiencing a similar issue, first try the steps detailed in this knowledge base article.

If you are using a Windows sytem, try completey uninstalling then reinstalling iTunes, as described in this knowledge base article.

WiFi problems Some users are reporting an inability to connect to WiFi networks after the iPhone OS 2.2 update.

One reader writes:

"After the 2.2 firmware upgrade, my phone does not pick up nor automatically connects to my wireless network, it is permanently on 3G. T tried rebooting my phone, didnt make any difference."

Among the potential fixes for WiFi connectivity issues are:

  • Turn WiFi off then on in Settings.
  • "Forget" the currently configured connection and allow it to reconfigure
  • Switch the router to WPA2
  • Remove all spaces from the WPA pass phrase
  • Remove all security from the router until a stable connection is attained then reconfigure the security
