I called Uconnect as I'm having the same problem with the MyGig in my wifes new Chrysler 2008 Town & Country. I was told by the operator at UConnect that they have LOTS of problems with Iphone and uconnect and it "Isn't a very good phone for Uconnect"
She had no knowledge of any attempts being made to rectify the problem. I'd like to bug apple about it, but in my opinion, Apple has proven themselves to be unwilling to work with other companies. I'm pretty p.o.ed to be honest. Here we are with a $600 Iphone that got dropped by two hundred dollars two months later, the simplest bluetooth head phones and connection devices don't work with it, you have to pay to turn your ipod music into ringtones, you can't can't view flash (flash!!!) on the internet, no voice dialing, etc etc etc. For all of it's GREAT features in regards to the ipod portion and the photo viewer, the phone itself is a hunking piece of crap that i CONSTANTLY lose my signal on.
