Slow 3G speeds on iPhone 5? This fixed my problem...

I may have just discovered a fix for the slow 3G issue affecting iPhone 5.


I was originally getting ~0.03 Mbps 3G download speeds in Chicago, and after following Sprint's documented procedure for updating the data profile, I was able to connect at ~1.5 Mbps, as tested using the Speedtest app.


Update the Data Profile - IPHONE 5 16GB



Be sure that you are connected via Wifi before attempting the update. The first attempted update failed when I wasn't connected to my Wifi network.


  1. From the home screen, tap Phone
  2. On the keypad, dial ##873283# and tap Call
  3. Tap OK. The handset will search for profile updates and install them.
  4. You should be receiving a confirmation screen that the profile has been successfully updated.



You can see the illustrated directions here...



Hope this helps!
