iPhone 4 & OEM iPod cable?

Anyone working with this combination? If so I have some questions...

1. Does the cable charge the phone?
2. Do you get playback through the stock HU from the Pandora app?
3. What happens when you get a call?
4. What happens if you want to make a call?

 

i have the older 16g 3gs and i have that cable. it has a usb and aux wire on it.

1. if you have a way to charge thru the usb cable, then yes, it will charge
2. my stereo use to play back thru the usb port, now i can only play it thru the aux port
3. unless you have a bluetooth stereo, you will still have to pick up the phone and talk
4. pick up the phone

 

Nobody else using this combination?

 

sorry charley, i roll evo style

 

I'm thinking that since the iPhone does everything a fancy HU does that I would need (nav, specifically) I'm not sure i want to go to the trouble of installing the Pioneer HU.
