Dont know if this has been answered before, but a brief search hasn't revealed anything. My Iphone 3G sometimes does not wake for a good minute. I will press the home or sleep/wake button to try and it just stays there. Sometimes it will wake and sleep straight away. Usually comes good just as my patience is wearing thin and I am about to do a hard reset. Anyone else had this? Should I exchange my Iphone or is this one of those "features" of the 2.0/2.01 software?
