1.) after sending a text, literally after clicking send, if i just set the phone down and do absolutely nothing, the sceen NEVER shuts off. it will literally sit there on the normal screen brightness and never dim. if i go into a message and act like im about to start typing, but do nothing, it does the same thing. if i get a reply during this period, it will shut the screen down normally. 2.) after deleting a picture from the camara roll, sometimes, not often, it will lock the camera roll and i cant do anything what so ever unless i shut down. this is only if i try to access it via the app (flower icon). however, i can go into the camara app, then click on the lower right to access the camara roll and it works normally. i have to reboot the phone everything to start functioning correctly. i am NOT jailbroken i am on 4.0.1 32gb iphone 4 anyone have same/similar issues?
