Ahh the "Port (null) gave it away. There is a bug in the iPhone 4 handling of settings do this...
1. Go into the iPhone EventPhone settings.
2. Change Port from 1025 to 1026.
3. Exit Settings.
4. Immediately go back into EventPhone settings and change it back to 1025.
5. Exit settings and try again. For some reason it leaves the Port NULL in iPhone4. I need to fix that bug.
Let me know how that goes!
