After the iOS 5.0.1 update, have you been experiencing a weird issue with your iPhone 4S in which the iPhone fails to recognize your contacts? Apple has recently released iOS 5.0.1 to the public in an attempt to fix the battery life issues that have been plaguing iPhone 4S owners on iOS 5.0 but this update seems to be causing more problems than providing solutions.

According to Paul Hontz of The Startup Foundry after the iOS 5.0.1 update the device only shows phone numbers when receiving calls or text messages and does not display the contact names though, all of the information is still contained in the contacts app. More over when that same contact responds to a text, the conversation begins in a new thread.

According to the sources this bug is isolated to those on the Verizon network with an iPhone 4S running the over-the-air (OTA) iOS 5.0.1 update.

Here is the fix:

If you have been experiencing this issue then you don’t have to worry anymore. Some people have experienced success in solving the problem by following these steps:

• Dial *228 on your iPhone 4S (A Verizon programming number).
• Press “1” to “Program or Activate you phone”.
• Once the call gets disconnected a prompt stating something like, “Settings updated.” will appear.
• Now open task manager by clicking on your Home Button twice and close your Phone, Message and Contacts Apps.
• After 5 minutes, open your Message App to verify fix.

Hoplfully this would fix the issue if this doesn’t help you, try pressing option “2” after dialing *288 on your phone, some customers have reported on the Apple Support Forums that this procedure has better results. If still having no luck? then unfortunately you may have to restore from a backup.

We hope that Apple fixes these minor bugs along with a proper battery solution in the upcoming update of iOS.
