So in 1.4.2, the Phone Charging option is gone?

I never have it on anyway, if your phone is not fully charged or near fully charged, why are you flying that you have to suck power from the RC? just my 2 cents.. Seems that i'd rather have the RC keep the power..
There can be various reasons for using that feature. I use it mostly when it's very cold outside because the iPhone battery doesn't do well on its own when it's super cold.
