Ok, I've had something odd happen with my 3GS. It just started this morning and while it's annoying, it's not a tragedy. I'm hoping someone else has experienced the same thing and might know of a fix short of doing a restore. Whenever I make or receive a call, once I put the phone to my ear, the screen goes dark (like it's supposed to). But it's started locking the screen...as if I had the call on speakerphone (when I don't). When the call is completed, and I go to hang up, I have to unlock the phone. The second part of this is that when I unlock the screen, it doesn't go straight to the call screen with the "end call" button at the bottom, but rather the screen appears as if I were on a speakerphone call, with the green bar at the top saying "tap here to return to call". I have to tap that in order to get to the call screen and finally end the call. Has anyone experienced this? If so, does anyone know of a fix? I'd rather not do a restore, but if I must, I will. It just seems odd since I haven't added anything to the phone in a few days. I did uncheck everything in Winterboard and return the phone to it's "native" state hoping that would show me that it was a theme or something that was causing it, but it still does it. Any help would be greatly appreciated!
