Ever since updating to iOS 4 I've had this weird problem, when launching the "Photos" app there's a 4-5 second pause before I'm able to select an album to view. I can see the list of albums but the status bar (where the time, carrier text, battery info is) is black and will only turn to grey 4-5 seconds later. Its also taking 4-5 seconds longer for the Camera app to open the shutter so I'm guessing its related. I've compared it to a friend's iPhone 3G also running iOS 4 and his is fine. To add more insult to injury, he's got about 200 more photos than I do so I'm guessing its not the number of photos which is causing this... Thoughts?
