So I opened my iTunes app to check out some new songs on iTunes and I noticed right when I did that the phone started to slow down and it was taking awhile for the information the load then all of a sudden the screen went black and the apple logo came up and it's like I turned the phone on and off but I didn't! Then I had to slide to unlock and it was back to normal. The only thing I can think of the reason for this happening is because I had some apps in the background running maybe. I was playing angry birds and didnt close the game out, facebook app open ect but I didn't have that many apps open. Anyways does anyone know why the screen went black and the phone seemed to start over without me doing a thing? Anyone experience this or know what I'm talking about? Thanks
