Just had an odd experience with iOS 7 which I’ll pass on. A couple of days ago, I received an iOS 7.0.2 update notification from Apple and it was downloaded, but not installed, on my 4S phone. I’ve been holding off doing the upgrade to wait for some glitches to get fixed. Yesterday, I finally decided to install it and that all went OK. When I went to start DPS 1.4.5, the DPS icon appeared on the screen for a fraction of a second, then the phone went back to its desktop. From there, I deleted DPS from both my phone and iTunes library, then downloaded it again from the app store. That solved the problem. Weird.
