In addition to the earlier string giving user a method to turn on and off 3G ("Using 3G loads data faster, but decreases battery life."), Apple has added two warning strings if a user tries to turn 3G on or off during an active phone call:
- "Disabling 3G will end your phone call. Are you sure you want to disable 3G?"
- "Enabling 3G will end your phone call. Are you sure you want to enable 3G?"
Apple appears to be fine tuning the 3G experience on the upcoming 3G-capable iPhone.
