I have had a problem with my new 3GS waking back up from being in the "sleep" mode. I will hit the home button and the sleep button and it won't do a thing. I will either have to attempt to sync it or hold down the home and sleep buttons until it wakes up, which doesn't always work but the sync does. I have also woke up the the iPhone and the backlight doesn't come on. I am probably going to call Apple about it tomorrow and see about getting a replacement sent out to me. I am mostly just curious if anyone else is having either of these problems.
