This morning I did the reset all settings option on my phone. After it booted up, the F90 found my iphone 3g, but displayed it as a string of characters (not the bluetooth profile name). When entering the pin number on the phone, the F90 also was listed as a string of characters and not the default bluetooth name. Regardless, it works now and it allowed me to transfer my contacts as well.
I'm using an iphone 3g with 2.2.1 software.
