I went to the Apple store and bought a new, off the shelf, iPhone 4 for my wife. (Added a second line on my account, now with 2 iPhone 4s) Got home, installed Facebook and Words with Friends and noticed that Push Notifications are not working on either app. Push notifications work fine on my iPhone 4 running 4.0.1. Her phone was already running 4.0.2 out of the box. Everything else is the same on both phones except for the OS version. I have reset all settings on her phone, rebooted, re-installed apps, checked notification settings... Any ideas? Should I try a factory restore on a 1 day old iPhone?
