For those that have iPhones and want to upgrade to iOS 4 and are using the a profile find solution below….
I had an issue after upgrading where it kept saying my iPhone password had expired, even after I changed it 5 times. To resolve the issue I ended up removing the profile and setup the Exchange and wireless manually. I am not aware of a way to setup the VPN manually. There may be a new profile builder utility out that creates a profile compatible with iOS 4.
