I have a few basic iPhone questions:
I hd been using a BB 8300, with a 2008 x5. The 8300 worked great.

2 weeks ago, I upgraded to a new AT&T 8900, because I was too stupid to wait. I have a lot of problems with this phone. The battery life is 1/3 the life I had with the 8300. Also, the "load only selected categories" for the bluetooth address book, no longer works. Which means that the Blackberry loads 1000 contacts to the BMW, every time. I also have assorted MAC / PC synchronization problems.

I am thinking of returning the 8900 for a new iPhone 3gs, 32 geg.

I am currently using the BB for the phone and my iPod touch w/iPod adapter, so I have the "best of both worlds." My BMW service adviser told me that "it is not recommended" to use an iPhone for both bluetooth phone and ipod music in the BMW. I really don't want to walk around with both an iPhone and an iPod. I also don't want to get into the 2nd profile, iTunes issue, because Apple fails to realize that people could own multiple devices.

So in a nutshell, how will an iPhone behave in a BMW when connected to both the bluetooth and the iPod adaptor?

How does the address book transfer work? Is there a way to control which contacts are loaded to the car?

Thank you for your help.
