Let me start off by saying that I just migrated from RR to CF and I can't believe I didn't do it sooner. Just installed CF4 w/ nav this morning and I love that it auto connects to my phone and Bluesoleil will grab the contacts. It works great!
That being said, I prefer to use bluetooth tethering (jailbroken running MYWI) instead of running an iphone USB cable to do it, and I am wondering if there is a way to have CF automatically initiate the tether (connection to PAN in bluesoleil). I can create a shortcut to launch the connection and drop it in my startup folder, but I prefer to have CF do it once the bluetooth drivers are fully initalized because sometimes the connection will launch before bluesoleil is up and running and the connection fails.
Worst case scenario, I will just run a cable and plug the phone in for a usb tether.
I have the USB tether option enabled, so as soon as I plug the iPhone in, it's immediately on the internet. I can enable the PAN through a shortcut on startup, but I guess I was hoping to keep it all bundled inside CF. I have the iPhone working through CF as far as calling and contacts go. I'm not too disappointed with that, other than sometimes on a boot it doesn't connect to the phone and I have to reboot. Not sure what that is all about.
The closest option I know of is MyWi ondemand but it only works with iPads. Perhaps you could contact their team and see if they can open up this feature. I too have been curious about an easier way to tether automagically.
