Hey guys, I just have a quick question. Just updgraded from a 3gs to a 4 and it was well worth it. I have noticed something and I wanted to see if someone had a fix. When I ended an incoming call on my 3gs, it automatically went into sleep mode after I hung up. Now on my 4 it takes me to "Slide to Unlock" instead of going black. I know it takes you back to your call log after you end an outgoing call but it never did it on on incoming call. I adjusted several things under "settings" but I'm having no luck. Any thoughts?
