    How does the effect of turning off cellular data differ from disabling 3G while in STANDBY?

    I ask because last night, my battery drained 10% with JUST wifi on. And cellular data is turned off but 3G is enabled. This drop was not happening before the 4.0.1 update, so I'm beginning to worry that this new software is killing my battery.

    Or just someone post the difference between the 3G option and cellular data.
